U.S. Route 101 in San Mateo County
Ramp Meters to go Green April 28, 2015
Watch For New Signals at On-Ramps

San Mateo County – The California Department of Transportation (Caltrans) will activate southbound ramp metering on U.S. Route 101 in San Mateo County beginning April 28, 2015.

What is Ramp Metering?
Ramp metering is a traffic management strategy using traffic signals and accompanying equipment and techniques to improve flow on the freeway system. It is intended to improve the safety of vehicle merging.

Motorists at newly activated ramp locations may experience operational delays during the first few days of operation. Caltrans staff will monitor the metered locations and make adjustments, and then fine tune the metering operations.

Southbound Activation
Meters at 17 on-ramps will be activated on southbound U.S. 101 between the San Francisco/San Mateo County line and State Route 92.

• Beginning Tuesday, April 28, 2015 on-ramp meters will be set to solid green during commute times to alert drivers to the new driving condition.

• On Tuesday, May 5, 2015, on-ramp meters will start cycling through red and green during southbound PM peak time from 2:30 p.m. to 8:00 p.m.

• On Tuesday, May 12, 2015, on-ramp meters will start cycling during southbound AM peak time from 6:00 a.m. to 10:00 a.m.

Drivers entering U.S. Route 101 where on-ramp meters are activated should stop at red and wait until the metering light turns green to enter U.S. Route 101. Caltrans will monitor traffic conditions and operate ramp meters as appropriate.

Additional Information: All on-ramps will operate at “1 car per green” except for one freeway to freeway connector ramp which will meter and operate at “2 cars per green”. The freeway connector is the eastbound State Route 92 to southbound U.S Route 101 Connector.

Following activation, Caltrans will monitor ramp metering vehicle activity and optimize systems as needed. In addition, ramp meters could be subject to time changes based on monitoring results.

I-80/I-680/SR 12 Interchange Project – Fairfield-April 2015 Update

State of California • Department of Transportation


Date: April 21, 2015
District: 4 – Oakland
Contact: Vince Jacala
Phone: (510) 286-5206

I-80/I-680/SR 12 Interchange Project – Fairfield
Increased Construction Activities resume April 2015

SOLANO COUNTY– Caltrans and its project partner, the Solano Transportation Authority (STA), have completed preliminary false work installation on the new I-80 Green Valley Road Overcrossing. The false work installation completed on April 9th required a full closure on I-80. The preliminary work marks a major milestone in this first package of the Interstate 80/Interstate 680/State Route 12 (I-80/I-680/SR 12) Interchange Project.

Pile-Driving Operations
With the metal beams of the new overcrossing installed, businesses and residents near the construction site may encounter increased noise due to the resumption of daytime pile-driving at the adjacent I-680/I-80 interchange, and the site of the new westbound I-80 to westbound SR 12 connector. Pile-driving is scheduled to resume in mid-April 2015 until fall 2015. Normal pile-driving hours are 9:00AM until 5:00PM Monday-Friday.

Increased Material Import
Motorists and residents near the construction zone may encounter temporary detours, intermittent lane closures, pile-driving, and see increased heavy construction equipment. All work is weather permitting.

Daytime travel delays may also be likely due to increased material hauling activity near Green Valley Road and Business Center Drive starting mid-April 2015. Motorists should watch for flaggers and changeable message signs.

Caltrans will make announcements when detour routes are necessary.

Caltrans to Close San Mateo Hayward Bridge
State Route 92
Two Weekends May 8-11 & May 22-25

San Mateo and Alameda Counties – Caltrans will close the San Mateo-Hayward Bridge over two full weekends, beginning, May 8-11, and continuing Memorial Day Weekend, May 22-25. The full closures for all eastbound and westbound lanes will begin at 10:00 PM on Friday and continue until 5:00 AM on Monday. (Including Memorial Day Weekend) There will be westbound lane closures as early as 7:00 PM and eastbound lane closures as early as 8:00 PM

The full closures will allow crews to resurface and treat the deck structure. In addition to the resurfacing, the closures will enable crews to perform routine maintenance. The activities will help prolong the service life of the bridge.

Commuters are asked to use alternate routes such as the Dumbarton Bridge, San Francisco Oakland Bay Bridge, or the southern route along Highway 237.

In the eastbound direction (Foster City) the on-ramps from Edgewater Boulevard and Metro Center Boulevard will be closed. In the westbound direction (Hayward) the on-ramps from Industrial Boulevard and Clawiter Road will be closed. All off-ramps will remain open. Mainline traffic will be guided to exit eastbound 92 at Foster City Boulevard and westbound 92 at Clawiter Road.

NOTE: Motorists will be able to travel up to the westbound off-ramp at Clawiter Road, and as far as the off-ramp at Foster City Boulevard during the closures.

Changeable message signs are posted throughout the Bay Area to notify motorist of the upcoming closures.

Please visit the San Mateo-Hayward Bridge project page or the Caltrans Twitter page for updates on the progression of the construction.

Southbound I-680 Marina Vista Ramp Closure Scheduled for
Interstate 680 Mococo Overhead Bridge Rehabilitation Project

Martinez, Contra Costa County – On April 27, 2015, Caltrans will close the southbound off-ramp from Interstate 680 to Marina Vista/Waterfront Road. The closure will remain in effect until October 2015 while the contractor removes the old off-ramp structure and builds a new structure.

• Detour: during this closure, southbound I-680 traffic will detour to the Arthur Road interchange, exit and cross under the freeway, return to northbound I-680, and exit at Marina Vista/Waterfront Road.
• Marina Vista and Waterfront Road will remain open during the extended ramp closure.
• Residents near Arthur Road may notice increased traffic when the detour begins.

If work is delayed due to weather conditions, it will be rescheduled for a later time. Please drive cautiously through the construction zone, follow the direction of flaggers, leave a safe traveling distance between your vehicle and the vehicle ahead of you, and Slow for the Cone Zone.

Project Information
Construction began in Summer 2014 and will continue through Winter 2015. Activities include performing a seismic retrofit of the southbound structure over Marina Vista/Waterfront Road and replacing the southbound Marina Vista/Waterfront Road off-ramp. In addition, a one-lane emergency access route will be built to connect southbound I-680 with northbound I-680. This access route will be used for emergency vehicles if an earthquake results in a closure of southbound I-680.
