[edit] Route description
It intersects with Highway 101 at the southern corner of Moffett Field. It also has a major intersection with Interstate 880. Westbound traffic can connect to Highway 85 southbound, but the eastbound traffic connection to 85 northbound is labeled as an exit for U.S. 101.
Half a mile from the highway's western terminus, to the I-880 intersection, Route 237 is constructed to Interstate standards, and is known as the Southbay Freeway. East of I-880 in Milpitas, it becomes a surface street, Calaveras Boulevard, and the highway designation terminates at the intersection with I-680.
Route 237 is known for the many Silicon Valley companies that line its route.
Before Route 237 was upgraded to freeway status in the mid-1990's, it was a 4-6 lane street, 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 possibile sites have been suggested, from Montague Expressway in North San Jose to Mission Boulevard in Fremont. One map printed before 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. [1]
