Santa Clara
County Sign Route G4

[Click here for a key to the symbols used. Some county routes were constructed with federal funds. These routes are indicated as FAP (Federal Aid Primary), FAU (Federal Aid Urban), or FAS (Federal Aid Secondary). If no funding source is shown, no federal funds were used. Note that while some segments seem to have the same attributes, they may differ in the county-local road number assigned to the segment, or in the Caltrans Map Sheet number.]

Routing

1. San Tomas Expressway in Campbell from Route 17 to the San Jose city limits (FAU, 2.22 mi)

2. San Tomas Expressway in San Jose from the San Jose city limits to Stevens Creek Blvd (FAU, 1.83 mi)

3. San Tomas Expressway from Stevens Creek Blvd to the Santa Clara city limits (FAU, 0.15 mi).

   Note: This segment makes no sense, as Stevens Creek Blvd is the Santa Clara city limit. Perhaps there was a post-1976 annexation.

4. San Tomas Expressway in Santa Clara from the Santa Clara city limits to US 101 (FAU, 4.10 mi)

   Status

   In June 2016, it was reported that there are plans to widen the expressway from south of Homestead Road to El Camino Real. Plans include:

   • Widening of the expressway from three to four lanes in each direction, from El Camino through Homestead, merging back to three lanes south of Homestead Road.
   • Extending the San Tomas Aquino trail on the west side heading south from El Camino, crossing Benton and ending at Homestead. A sidewalk will be installed along the east side of the expressway.
   • Adjacent to the new trail and sidewalk, installing 10-foot-high walls to replace the existing 6-foot-high walls.
   • Making improvements to both the intersection and traffic signals at Benton and Homestead, including adding double left-turn lanes on Homestead.

   The carpool lane may be temporarily closed.

   In September 2019, it was reported that Santa Clara County plans to turn off the electronic signs and beacons that were installed decades ago to indicate carpool lane operation, and remove them. The county will rely on the black-and-white carpool signs already installed that show the carpool hours. The yellow flashing lights were put in place to provide drivers extra warning.

5. Montague Expressway in Santa Clara from US 101 to the Guadalupe River (FAU, 1.62 mi)

6. Montague Expressway from the Guadalupe River to the San Jose city limits (FAU, 0.76 mi).

   Note: This segment makes no sense, as the Guadalupe River is the San Jose city limit. Perhaps there was an annexation of Santa Clara county land post-1976 with either Alviso, Barryesa, or North San Jose.

7. Montague Expressway in San Jose from the San Jose city limits to the Milpitas city limits (FAU, 2.10 mi)

8. Montague Expressway in Milpitas from the Milpitas city limits to I-680 (FAU, 1.33 mi)

   Status

   It was reported in October 2016 that South Milpitas Boulevard will be completely closed from Montague to Garden Street for five weeks beginning Oct. 14, 2016 for a big water project that will also widen and raise Montague to accommodate the flood control measures and fill the carpool lane gap.
