Carpools, motorcycles, and clean air vehicles are not charged. All tolls are collected using an open road tolling system, and therefore there are no toll booths to receive cash. Each vehicle using the HOT lanes
1890-452: The ban for short periods to reduce traffic congestion when major accidents occur on I-880 or I-238. The truck prohibition has been in effect since before the freeway was built in 1963 as part of US 50. Both the FHWA and Caltrans imposed the restriction, partly because the city of Oakland already had a truck ban through the area prior to the freeway's construction. Since then, the restriction

The 323 auxiliary routes generally fall into three types: spur routes , which connect to or intersect
2394-1041: The former generally gets more traffic than the latter. For decades, the trucking industry lobbied to have the ban removed but was unsuccessful due to local opposition. In 2000, the California State Legislature passed Assembly Bill 500, adding the I-580 truck restriction into the California Vehicle Code. A collaborative study by the Environmental Defense Fund , Google , and the University of Texas at Austin used Google Street View cars equipped with air quality monitors to measure pollution data through Oakland. It found that along I-880, concentrations of black carbon were 80 percent higher, concentrations of nitrogen dioxide were 60 percent higher, and concentrations of nitric oxide were at least double than those along I-580. This has led community leaders to revisit
2457-494: The health care and social assistance industry, followed by the retail trade industry with 1,073 employees and accommodation and food service with 1,044 employees. The health care and social assistance industry provided $ 1.1 billion in sales, shipments, receipts or revenue in 2012, which is the highest of all industries, and it is followed by the retail trade industry, which had a value of $ 324.1 million in sales, shipments, receipts or revenue. The median household income of residents

I-580 provides a connection from the Bay Area to the southern San Joaquin Valley and Southern California via I-5, as I-5 bypasses the Bay Area to the east. A portion of I-580 is called the MacArthur Freeway , after General Douglas MacArthur . Other portions are named
2583-550: 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

2646-413: The most part, the I-580 freeway in this segment was constructed over or alongside the right-of-way of US 50 , previously part of the old Lincoln Highway , during the course of the late 1960s and early 1970s. The segment which begins at the split with I-205 was constructed during the same period of time over a new right-of-way to a junction with I-5, running through some low hills on the west side of
2709-542: 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
2772-489: 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
2835-418: The population was Hispanic or Latino of any race. The census reported that 98.0% of the population lived in households, 0.4% lived in non-institutionalized group quarters, and 1.5% were institutionalized. Of the 22,348 households 36.1% had children under the age of 18 living in them, 54.3% were opposite-sex married couples living together, 12.6% had a female householder with no husband present, and 5.2% had
2898-637: The potential designation has gained popular favor with the community. Trucks over 4.5 short tons (4.1 t; 4.0 long tons) are prohibited through Oakland between Grand Avenue and the San Leandro border. Specifically, eastbound trucks cannot travel beyond Grand Avenue/Lakeshore Avenue (exit 21B), and those going westbound must get off at MacArthur Boulevard/Foothill Boulevard (exit 30). They are instead instructed to take I-238 in Castro Valley and then I-880 through Oakland as an alternative route. The California Highway Patrol may however temporarily lift

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
3150-516: 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
3213-472: The three-digit highways they do intersect with. Examples include: A bypass route may traverse around a city, or may run through it with the mainline bypassing.
