U.S. Route 2 ( US 2 ) is a component of the United States Numbered Highway System that connects the city of Everett in the U.S. state of Washington to the Upper Peninsula of Michigan , with a separate segment that runs from Rouses Point, New York , to Houlton, Maine . Within Washington, the highway travels on a 326-mile-long (525 km) route that connects the western and eastern regions of the state as a part of the state highway system and the National Highway System . US 2 forms parts of two National Scenic Byways , the Stevens Pass Greenway from Monroe to Cashmere and the Coulee Corridor Scenic Byway near Coulee City , and an All-American Road named the International Selkirk Loop within Newport .

75-629: US 2 begins in Everett at an intersection with State Route 529 (SR 529) in Everett and travels east to an interchange with Interstate 5 (I-5). The highway travels over the Cascade Range through Stevens Pass , connecting the western and eastern parts of the state. US 2 becomes concurrent with US 97 from Peshastin to Orondo , crossing the Columbia River in Wenatchee on

150-612: A partial cloverleaf interchange with Broadway, which was SR 529 before 1991 and US 99, and Marine View Drive, which continues southeast to I-5 at exit 195. The highway travels over the Snohomish River onto Smith Island, part of the Delta neighborhood of Everett that is named after the delta of the Snohomish River located to the southwest. The Snohomish River crossing was the busiest segment of SR 529 in 2007, with an estimated daily average of 33,000 motorists. Crossing

225-559: A bypass of the congested SR 528 corridor, which is often blocked by trains. The project is planned to concurrently occur with rehabilitation work on both spans of the Steamboat Slough Bridge and the northbound span of the Snohomish River Bridge; the latter bridge will be closed for four months in late 2023 for WSDOT to conduct the work in compliance with United States Coast Guard regulations. The entire highway

300-826: A canyon that drained to the Columbia near the current mouth of Moses Coulee. These side drainages are still visible today along the coulee walls as truncated streambeds, interspersed with gable-like highlands. The Okanogan lobe of the Cordilleran Glacier moved down the Okanogan River valley, covering 500 mi of the Waterville Plateau and blocked the ancient route of the Columbia River, backing up water to create Glacial Lake Columbia and Lake Spokane . Initially water discharged from Lake Columbia by running up through

375-675: A diamond interchange with 88th Street. The two-lane road continues southeast along the Scenic Subdivision of the Northern Transcon , a BNSF rail line, into Monroe . The highway travels past the Evergreen State Fairgrounds and intersects SR 522 before entering downtown Monroe. US 2, now part of a National Scenic Byway named the Stevens Pass Greenway, continues through the city of Monroe and forms

450-531: A freeway along the Stevens Pass corridor. In 2023, the Sultan city government endorsed plans to widen US 2 to four lanes and replace several intersections with roundabouts. In addition to the freeway expansion, WSDOT is considering a total replacement of the westbound Hewitt Avenue Trestle that would cost between $ 750 million to $ 1 billion. One of the options in the early feasibility study conducted in 2017 included

525-653: A road between the two cities across the Snohomish River delta was needed. At the time, the only route between the two cities was a winding road traveled around the northeast side of the delta. The first bridge across the delta was opened the following year, connecting Everett to Smith Island. In 1913, the Pacific Highway was added to the state highway system and used Broadway (former SR 529) in Everett and State Avenue in Marysville to travel between Seattle and

600-412: A roundabout. From Monroe to Gold Bar , US 2 would be expanded to a four-lane highway, with a roundabout connecting the highway to the city of Gold Bar, and become a two-lane highway with wider shoulder lanes to Skykomish. Seasonal traffic congestion in the Sultan area, which causes backups that overflow onto side streets, have inspired proposals to build an additional bypass, a two-street couplet , or

675-528: A series of surveys on its highways in the state to measure traffic volume. This is expressed in terms of annual average daily traffic (AADT), which is a measure of traffic volume for any average day of the year. In 2013, WSDOT calculated that the busiest section of US 2 within Washington was the Hewitt Avenue Trestle above the Snohomish River east of Everett , carrying over 76,000 vehicles, while

750-549: A short connector to downtown Wenatchee, and US 97 Alternate , an alternate route to Chelan , in Sunnyslope before crossing the Richard Odabashian Bridge over the Columbia River and into Douglas County . The two highways continue east into East Wenatchee and turn north at the western terminus of SR 28 . US 2 and US 97 continue north between the Columbia River to the west and Badger Mountain to

825-591: A transfer of the Ebey Slough Bridge to local control in the late 1980s, but dropped the proposal. In May 1983, the location of a new home port for the United States Navy was narrowed down to Everett and Seattle, as proposed by Senator Henry M. Jackson ( D ), who died later that September. Everett was selected in April 1984 and the groundbreaking ceremony was held on November 9, 1987. On September 5, 1991,

900-613: A vehicle toll, which sparked public outcry on social media. The study also lists an increased gas tax , federal grants, and public-private partnerships as potential revenue sources for the project. Washington State Route 529 State Route 529 ( SR 529 , officially the Yellow Ribbon Highway ) is a Washington state highway that connects the cities of Everett and Marysville . The 7.88-mile-long (12.68 km) roadway extends north from an interchange with Interstate 5 (I-5), numbered exit 193, past

975-548: Is in Snohomish County . SR 529 also has a 0.20-mile (0.32 km) long spur route in Everett that extends from SR 529 to Interstate 5 (I-5) northbound, numbered exit 194. Since exit 193, the southern terminus of SR 529, only serves I-5 southbound, the spur route was established in 1991 to complete the interchange. Exit 194 also serves U.S. Route 2 (US 2), which terminates at SR 529. In 2007,

1050-415: Is now dry, but during glacial periods, large outburst floods with discharges greater than 600,000 m /s (21,000,000 cu ft/s) carved the channel. While it's clear that glacial floodwaters passed through and contributed to the erosion of Moses Coulee, the age of those waters, thus the origins of the coulee are less clear. No clear connection between the head of the coulee and major flood routes to

1125-652: Is signed as a spur route of US 395. The highway continues west of Mead and intersects SR 206 , a road serving Mount Spokane State Park , before becoming a four-lane divided highway parallel the Kooteani River Subdivision of the BNSF Northern Transcon. US 2 travels north along the Little Spokane River through Colbert and Chattaroy before leaving Spokane County and entering Pend Oreille County . The divided highway ends at

1200-530: Is the location of the Everett Public Library , listed on the National Register of Historic Places , and Marine View Drive, where the road turns north to parallel a BNSF Railway route and serve the Everett waterfront, which includes Naval Station Everett and Jetty Island , accessed via a ferry near 10th Street. Leaving the waterfront, SR 529 parallels the Snohomish River southeast to

1275-482: The 2020 Washington Labor Day fires more than 400,000 acres of shrub-steppe was burned including 3,000 acres of Moses Coulee Preserve in just half a day. The Nature Conservancy has established the Moses Coulee Preserve, which is a 3,588-acre (14.52 km ) contiguous, intact shrub-steppe habitat. It is located 2 miles (3.2 km) south of Jameson Lake near the head of Moses Coulee. It provide habitat for

1350-603: The Canada–US border . The Pacific Highway between Everett and Marysville, named the Vernon Road, was paved in 1916 and paid by a county road bond issue. The highway was later signed as State Road 1 in 1923, which became the Washington segment of U.S. Route 99 (US 99) during the creation of the United States Numbered Highways in 1926. Since the bridges over the Snohomish River delta weren't complete at

1425-683: The Columbia Plateau , intersecting SR 172 at Farmer . US 2 becomes concurrent with SR 17 as it descends into the Grand Coulee south of Banks Lake , becoming part of the Coulee Corridor Scenic Byway . The byway travels off US 2 and onto SR 155 east of Coulee City at Fordair , continuing north through Grant County towards the Grand Coulee Dam . US 2 travels east into Lincoln County between

1500-726: The Columbia River Basalt Group , a large igneous province that lies across parts of the states of Washington , Oregon , and Idaho in the United States of America . During late Miocene and early Pliocene times, one of the larger flood basalts ever to appear on the earth 's surface engulfed about 163,700 km (63,000 mile ) of the Pacific Northwest, forming a large igneous province with an estimated volume of 174,300 km . Eruptions were most vigorous from 17—14 million years ago, when over 99% of

1575-668: The Ebey Slough . US 2 turns southeast at the east end of the trestle in Cavalero at an interchange with SR 204 , which serves Lake Stevens . The limited-access road travels around the city of Snohomish , intersecting Bickford Avenue in an at-grade intersection and SR 9 in a diamond interchange . US 2 turns south and crosses over the Pilchuck River and the Centennial Trail before its limited-access road ends at

1650-754: The Everett Memorial Stadium , home of the Everett AquaSox , Everett Avenue (current SR 529) and the Everett Community College to join current SR 529 at the Marine View Drive interchange. Between 2005 and 2008, exit 192 on I-5 was reconstructed. A new flyover ramp from I-5 northbound to Broadway northbound was added and the 41st Street interchange was transformed into a single-point urban interchange . As early as 1915, citizens of both Everett and Marysville proposed that

1725-668: The Idaho state line at the northern terminus of SR 41 in Newport and ID-41 in Oldtown, Idaho . US 2 follows the route of several wagon roads and early state highways that themselves followed the route of the Skykomish River and the Great Northern Railway , a transcontinental railroad that was completed in 1893. A wagon road from Snohomish to Skykomish was completed in

1800-531: The Idaho state line in Newport via a short branch route. US 10 was relocated to a southern route in 1939, crossing the Columbia River at Vantage , and the former route was replaced by US 10 Alternate the following year. A proposal from representatives of the highway departments of Idaho and Washington to extend US 2 to Everett was considered by the AASHO's U.S. Route Numbering Committee in January 1946, but

1875-441: The Pacific Highway in 1913, which became State Road 1 in 1923 and US 99 in 1926, but the cutoff actually opened in 1927. State Road 1 became Primary State Highway 1 (PSH 1) in 1937 and PSH 1 became US 99 in 1964. After US 99 was decommissioned, SR 529 was established in 1971. Naval Station Everett was opened in 1991 and SR 529 was realigned on Everett Avenue and Marine View Drive to serve

1950-630: The Richard Odabashian Bridge . The highway continues east across the Columbia Plateau in Central Washington and crosses the Grand Coulee while concurrent with SR 17 west of Coulee City. The highway travels into Spokane concurrent with I-90 and US 395 and leaves both highways continuing northeast to Newport.

US 2 travels northeast through Country Homes on the Newport Highway to an interchange with the North Spokane Corridor , an incomplete freeway bypass of Spokane that

2100-505: The Snohomish area showed the current and former routes in Everett already complete. By 1898, citizens of both Everett and Marysville were interested in a road that would traverse the Snohomish River delta. A 1911 map of the Mount Vernon area showed the route in Marysville, but the bridges between Everett and Marysville were railroad bridges. The roads were combined with other highways to form

2175-773: The Tye River past the town of Skykomish and the Cascade Tunnel towards Stevens Pass . The pass, located 4,061 feet (1,238 m) above sea level, is also home to the Stevens Pass Ski Area and a trailhead for the Pacific Crest Trail while serving as the point in which US 2 crosses into the Wenatchee National Forest in Chelan County . The highway continues east down Nason Creek to Coles Corner ,

2250-458: The Columbia River formed Glacial Lake Columbia and Lake Spokane , larger lakes than Lake Roosevelt, which is currently backed up in the same location behind the Grand Coulee Dam. A precursor to glacial-flood-cut Moses Coulee existed prior to the glacial floods as a drainage basin with a number of side streams, draining the southern portion of the plateau. These streams had combined into

2325-481: The Columbia River in 1975, while the former alignment was designated as SR 285 in 1977. The present two-lane expressway north and east of Snohomish was approved in 1969 and opened in October 1983; it was originally intended to also include an unfinished bypass of Monroe . US 97 had its concurrency with US 2 extended from Sunnyslope to Orondo along the east side of the Columbia River in 1987 after US 97

Now named State Avenue, the street passes through the waterfront area of Downtown Marysville and the Marysville Mall before ending at the intersection with Fourth Street, signed as SR 528 while State Avenue continues north to Smokey Point . Prior to 1991, SR 529

2625-487: The amendment did not make it into the final bill. The Washington state highway system was changed to its current "sign route system" beginning in January 1963 with a state highway renumbering . Under the new system, Interstate highways, U.S. routes, and state routes replaced the primary and secondary highways and were codified under the Revised Code of Washington in 1970. US 2 was re-routed around various cities over

2700-460: The basalt was released. Less extensive eruptions continued from 14—6 million years ago. These lava flows have been extensively exposed by the erosion resulting from the Missoula Floods , which laid bare many layers of the basalt flows on the edges of the plateau along the course of Moses Coulee. Pleistocene glaciers advanced onto the Waterville Plateau, with the Okanogan Lobe of

2775-547: The completion of the Hewitt Avenue Trestle and a bypass of Snohomish . A series of projects is planned to improve the US ;2 corridor between Snohomish and Skykomish by expanding the highway near various cities and the completion of a bypass around Monroe . US 2 is defined by the Washington State Legislature as SR 2, part of the Revised Code of Washington as § 47.17.005 . Every year, WSDOT conducts

2850-402: The early 2000s, WSDOT began planning a series of 56 projects to improve the US 2 corridor between Snohomish and Skykomish, where the highway is two lanes wide and has been the site of over 2,600 collisions between 1999 and 2007 that caused 47 fatalities. A study, conducted by WSDOT in 2007, divided the corridor into four segments, each with a specialized development plan. The study suggested

US 2 and US 97 split at Orondo, with US 97 continuing north along the Columbia River towards Chelan and US 2 traveling east up Pine Canyon onto the Waterville Plateau . The highway travels through the town of Waterville via several turns on city streets before heading due east across

3000-503: The expansion of the limited-access highway from Snohomish to the western city limits of Monroe to four lanes, including an interchange at Bickford Avenue that was later completed in September 2013. A wider median with rumble strips was added to some sections of US 2 between Snohomish and Monroe in 2019. WSDOT plans to move US 2 onto a northern bypass of Monroe, which would avoid the business district and intersect SR 522 with

3075-464: The head of Grand Coulee and down through Foster Coulee to rejoin the Columbia River. As the glacier moved further south, Foster Coulee was cut off and the Columbia River then discharged through Moses Coulee, which runs southward slightly to the east of the ancient and current course of the Columbia. As the Okanogan lobe grew, it blocked Moses Coulee as well; the Columbia found the next lowest route through

The state of Washington began maintaining sections of what would become US 2 with the extension of State Road 7 in 1909, from Peshastin to Spokane on the Sunset Highway and later State Road 2 . In addition to State Road 2, State Road 23 was created in 1915, traveling north from Spokane to Newport, and

3450-611: The least busiest section of US 2 is in Moses Coulee , carrying 630 vehicles. The entire route of US 2 within Washington is designated as part of the National Highway System , classifying it as important to the national economy, defense, and mobility. WSDOT designates US 2 as a Highway of Statewide Significance, which includes highways that connect major communities in the state of Washington . US 2 begins in downtown Everett, with its eastbound lanes starting at

3525-739: The main water gap in the Saddle Mountains, Sentinel Gap . Although the Columbia River flowed only for a short period through Moses Coulee, this period included one or more of the tremendous flows from the Missoula Floods . As the Okanogan lobe melted, the upper portions of Moses Coulee were littered with clear evidence of its passing in the Withrow Moraine . The glacier left behind a blanket of glacial till, up to 50 feet (15 m) thick in places. This glacial till, made up of clay, silt, sand, gravel, cobblestones, and erratic boulders, covers most of

3600-434: The new naval base. The former route of the highway, now named Broadway, had an interchange with I-5 that was reconstructed between 2005 and 2008 to include high-occupancy vehicle (HOV) lanes and now includes a single-point urban interchange with 41st Street. SR 529 begins at exit 193 on I-5 , a half-diamond interchange with Pacific Avenue in downtown Everett. The highway turns north on Maple Street and travels along
