26-456: Interstate 885 ( I-885 ) and North Carolina Highway 885 ( NC 885 ) is an 11.5-mile (18.5 km) auxiliary Interstate Highway and state highway in the U.S. state of North Carolina. It links NC 540 and I-40 to I-85 in the Durham area. The route consists of two previously preexisting segments of freeway— NC 147 to the south and US 70 to the north—connected by
52-470: A junction that was reconstructed as a compressed diamond interchange . After continuing north and meeting Cheek Road, the Interstate ends at a semi-directional T interchange with its parent route, I-85. Tolls along NC 885 are charged by electronic toll collection (ETC) and are enforced by video cameras. Several gantries are located along the route and entrance/exit ramps, where they collect tolls via

One such project is the AASHTO Road Test , which is a primary source of data used when considering transport policies and the structural design of roads. Much of AASHTO's current research is performed by the National Cooperative Highway Research Program (NCHRP) which

Some examples of beltways include: American Association of State Highway and Transportation Officials The American Association of State Highway and Transportation Officials ( AASHTO ) is a standards setting body which publishes specifications, test protocols , and guidelines that are used in highway design and construction throughout
130-460: A short segment of new freeway between NC 147 and US 70, the section of US 70 between Cheek Road and the connector was being realigned and widened to six lanes. Work at the interchange between NC 147 and the connector was expected to be completed in June 2018, but work in that area continued past that date, as the completion date got pushed back to mid-2022. In May 2022, AASHTO approved
156-458: A state. There are three states that have no auxiliary Interstate Highways: Alaska, Arizona, and New Mexico. North Dakota has an auxiliary route, but it is unsigned , and Wyoming's does not meet Interstate Highway standards. Auxiliary Interstates are divided into three types: spur , loop , and bypass routes. The first digit of the three digits usually signifies whether a route is a bypass, spur, or beltway. The last two digits are derived from

The voting membership of AASHTO consists of the Department of Transportation of each state in the United States, as well as those of Puerto Rico and the District of Columbia . The United States Department of Transportation has
234-654: The East End Connector , which opened to traffic on June 30, 2022. NC 147 was truncated and removed from the southern half of the Durham Freeway and the northern section of the Triangle Expressway , which were redesignated I-885 and NC 885, respectively. The route is cosigned with US 70 from exit 10 to its northern terminus. The route provides a continuous freeway bypass east of downtown Durham and also provides freeway access from I-40 and I-85 to

Drivers who do not participate in the ETC program will receive a bill in the mail and will have 30 days from date on bill before additional fees and civil penalties are applied. The first section of what eventually became I-885 to be constructed was the portion of US 70 between the East End Connector and I-85, completed by 1957 with US 70 relocated onto it. The East End Connector first appeared in Durham's 1959 thoroughfare plan but
286-527: The Research Triangle Park and (via NC 147) to downtown Durham. NC 885 begins at the interchange with NC 540. The whole route carries the moniker of the Triangle Expressway , which it inherits from the portion of NC 540 south of the aforementioned interchange. It has a single interchange with Davis Drive and Hopson Road between its termini. NC 885 ends at the interchange with I-40, at which I-885 promptly begins. Running north on

In the meantime, as part of a larger widening project on I-85, the early 2000s saw the reconstruction of the US ;70 freeway between I-85 and Cheek Road, widening the section to six lanes and bringing it up to modern Interstate Highway standards as well as adding the missing movements at the interchange with I-85. The I-885 designation did not become public knowledge until
338-508: The Durham Freeway (former NC 147) through the Research Triangle Park , three closely-spaced interchanges link the route to East Cornwallis Road, T.W. Alexander Drive, and Ellis Road. At the Durham city line, NC 147 begins and diverges toward downtown Durham, while I-885 heads northeast on the East End Connector before joining US 70, curving to the northwest concurrent with the latter route. The freeway turns due north as it comes to US 70 Business (US 70 Bus)/ NC 98 at

However, the Durham Chapel Hill Carrboro Metropolitan Planning Organization (DCHC MPO) removed this proposal from its plans, leaving this project in question. In 2012, a proposal to extend NC 147 (now NC 885) from its current southern terminus south to McCrimmon Parkway, in Morrisville , was scheduled for re-prioritization. As of October 2020,
390-452: The United States. Despite its name, the association represents not only highways but air, rail, water, and public transportation as well. Although AASHTO sets transportation standards and policy for the United States as a whole, AASHTO is not an agency of the federal government; rather it is an organization of the states themselves. Policies of AASHTO are not federal laws or policies, but rather are ways to coordinate state laws and policies in
416-478: The establishment of I-885; this was followed with the East End Connector opening to traffic on June 30, 2022, at which point I-885 was signed on the entirety of its designated corridor. The portion of former NC 147 from NC 540 to I-40 was redesignated as NC 885. The NCDOT 2020–2029 Final STIP released in September 2019 indicated a project that would widen 3.9 miles (6.3 km) of I-885 to six lanes from

Its name was changed to American Association of State Highway and Transportation Officials on November 13, 1973. The name change reflects a broadened scope to cover all modes of transportation, although most of its activities are still specific to highways. While AASHTO
468-550: The main Interstate Highway. For instance, I-115 contains an odd number in the first digit (1), which indicates that this freeway is a spur. The last two digits signify the highway's origin. In this case, the "15" in I-115 shows that it is a supplement to I-15 . Exceptions to the standard numbering guidelines exist for a number of reasons. In some cases, original routes were changed, extended, or abandoned, leaving discrepancies in
494-542: The parent route at one end; bypasses , which connect to the parent route at both ends; and beltways , which form a circle that intersects the parent route at two locations. Some routes connect to the parent route at one end but to another route at the other end; some states treat these as spurs while others treat them as bypasses. Like the primary Interstate Highways , auxiliary highways meet Interstate Highway standards (with rare exceptions ). The shorter auxiliary routes branch from primary routes; their numbers are based on
520-489: The parent route's number. All of the supplement routes for Interstate 95 (I-95) are designated with a three-digit number ending in "95": I-x95. With some exceptions, spur routes are numbered with an odd hundreds digit (such as I-395 ), while bypasses and beltways are numbered with an even hundreds digit (such as I-695 ). Because longer Interstates may have many such supplemental routes, the numbers can repeat from state to state along their route, but they will not repeat within

Later sign plans from NCDOT indicated that I-885 was expected to be signed immediately upon the completion of the East End Connector, pending approval from the FHWA. Construction on the East End Connector began in April of the following year. In addition to the construction of
598-415: The same Interstate, some states treat these as bypasses while others treat these as spurs—see Spur route above. A beltway (also known as a loop route ) completely surrounds a metropolitan city, and it is often connected with multiple junctions to other routes. Unlike other auxiliary Interstate Highways (and by extension, all primary Interstate Highways ), beltways do not have termini; however, they have
624-516: The system. In other cases, it may not be possible to use the proper number because the limited set of available numbers has been exhausted, causing a "non-standard" number to be used. A spur route 's number usually has an odd number for its first digit. It is usually one of the following: Examples include: Sometimes, a three-digit Interstate Highway branches off from another three-digit Interstate Highway. These spurs do not connect directly with their parent highways, but are associated with them via

In a typical 3-digit Interstate Highway, bypasses usually have both its two termini junctioned with another Interstate highway. Bypass routes are preceded by an even number in the first digit. Examples include: In the case of an auxiliary Interstate highway which has both ends at Interstates but not

The portion of NC 147 concurrent with the proposed Interstate opened in the early 1970s, including accommodation for an interchange with the Connector. The project would resurface in the 1990s when the North Carolina Department of Transportation (NCDOT) studied it again, but it would not receive funding until it appeared in
