Автомагистраль 237: Велодорожка и Экспресс-полосы в Калифорнии

Highway in California

The Highway 237 Bikeway is a 5 mile (8 km) pedestrian and bicycle path that parallels State Route 237. The majority of the path is separated from vehicular traffic, however, two sections comprising a total of 1.5 mile (2 km) follow an on street alignment adjacent the freeway. This bikeway serves as an important connector in the network of trails in San Jose and Santa Clara County. It intersects with the Guadalupe River Trail, which provides access to Downtown San Jose, as well as the San Tomas Aquino Creek and Coyote Creek trails.

The SR 237 Express Lanes, the 5 mile (8 km) high occupancy toll (HOT) lanes along Route 237 in both directions between Mathilda Ave in Sunnyvale and I 880 in Milpitas, opened on March 20, 2012, east of North First Street and on November 22, 2019, up to Mathilda Ave. Instead of terminating exactly at the I 880 interchange, the Express Lanes continue along an connector ramp to I 880, so that eastbound Express Lane users merge directly into the I 880 northbound HOV lane (which itself becomes an Express Lane), and I 880 southbound Express Lane users can directly enter Route 237's westbound Express Lane. as of 2020, the HOT lanes' hours of operation is weekdays between 5:00 am and 8:00 pm. Solo drivers are tolled using a congestion pricing system based on the real time levels of traffic. Two person carpools and clean air vehicles with a solo driver are charged 50 percent of the posted toll. Carpools with 3 or more people and motorcycles 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 is required to carry either a FasTrak Flex or CAV (Clean Air Vehicle) transponder, with its switch set to indicate the number of the vehicle's occupants (1, 2, or 3 or more). Solo drivers may also use the FasTrak standard tag without the switch.

Before Route 237 was upgraded to freeway status in 1994–1995, it was a four lane expressway with at grade intersections, known as Alviso Milpitas Road or Milpitas Alviso Road depending on different maps showing the description. The Route 237 corridor has long been sought as a location for a freeway connector between Interstates 680 and 880. Many possible sites have been suggested, from Montague Expressway in North San Jose to Mission Boulevard in Fremont. One map printed before Route 237's construction to freeway standards between Alviso and 880 showed a new freeway across bay wetlands between Alviso and the Scott Creek Road interchange in South Fremont. Grading and underpasses for a freeway interchange are presently visible along 680 near Scott Creek Road.
