Highway Safety Improvement Program (HSIP)

In November 2016, the City of Grand Terrace was awarded the HSIP Grant from Caltrans. The HSIP Grant will fund safety improvements at major intersections on Mt. Vernon Avenue. The total value of the grant is $435,700.

Environmental Document

Project Description:

Project area includes the Mt. Vernon Avenue corridor from Canal Street/Grand Terrace

Road to Pico Street with an emphasis on the following intersections:

• Mt. Vernon Avenue and Canal Street/Grand Terrace Road
• Mt. Vernon Avenue and Barton Road
• Mt. Vernon Avenue and De Berry Street
• Mt. Vernon Avenue and Van Buren Street
• Mt. Vernon Avenue and Pico Street

The proposed improvements include the installation of radar speed feedback signage along the stretch of Mt. Vernon Avenue between Canal Street/Grand Terrace Road and Pico Street, street and pedestrian crossing pavement marking improvements at Grand Terrace Road, De Berry Street, and Pico Street, and enhanced street lighting along selected segments of Mt. Vernon Avenue.

Based on a cumulative analysis of collisions and the City’s evaluation of high priority corridors for safety improvement needs, the City staff recommends the installation of three countermeasures along Mt. Vernon Avenue to achieve significant safety reductions along this corridor: 1) Installation of radar speed feedback signs, 2) Improvements to roadway and crosswalk pavement markings along impacted intersections and approaches, and 3) Installation of street lighting at strategic locations where roadway and intersection visibility is poor.

No vegetation is expected to be removed to make the project improvements. Any digging will comply with the required standards for footing placement of segment lighting and signs. Street lights and signs are expected to be solar powered thus reducing if not eliminating the need to dig for hard wiring.

Bid Addendum #1 for Traffic Signal Maintenance 4-22-22.pdf


A roundabout is an intersection where traffic travels around a central island in a counter-clockwise direction. Roundabouts do not have bicycle lanes, so traffic must share the road. Vehicles or bicycles entering or exiting the roundabout must yield to all traffic including pedestrians:

When you approach a roundabout:

  • Cars in the left lane have the right-of-way. 

  • Slow down as you  approach the  roundabout.

  • Yield to pedestrians and bicyclists crossing the roadway.

  • Watch for signs and/or pavement markings that guide you or prohibit certain movements.

  • Enter the roundabout (heading to the right) when there is a big enough gap in traffic to merge safely.

  • Travel in a counter-clockwise direction. Do not stop or pass.

  • Signal when you change lanes or exit the roundabout.

  • If you miss your exit, continue around until you return to your exit. For roundabouts with multiple lanes, choose your entry or exit lane based on your destination as shown in the graphic. For example, to:

    • Turn right at the intersection (blue car), choose the right-hand lane and exit in the right-hand lane.

    • Go straight through the intersection (red car), choose either lane, and exit in the lane you entered.

    • Turn left (yellow car), choose the left lane, and exit.
