Avoiding Highway 4 traffic is easier than ever with the opening of 850 additional parking spaces at BART’s popular Antioch Station. The new lot is BART’s latest effort to welcome riders back and to encourage East Contra Costa County residents to take BART instead of driving.
Riders at all stations can now pay the daily fee or reserve single day or multi-day parking through the official BART app. The process to purchase monthly parking or join the wait list has also moved to the official BART app. There is no longer a wait list for monthly parking at Antioch.
The parking expansion and access improvement project included:
- Construction of 850 fee parking stalls
- Dedicated ADA accessible sidewalk to the Antioch Station
- Improved passenger pick-up/drop-off and bus lane circulation
- Improved wayfinding for pedestrians, cyclists, transit passengers, and drivers
- Construction of a multi-use pedestrian/bicycle path along Slatten Ranch Road between Hillcrest Road and the station.

The California Department of Transportation and the Contra Costa Transportation Authority are constructing two new connector ramps, one connecting westbound State Route 4 (SR-4) to northbound SR-160, and one connecting southbound State Route 160 (SR-160) to eastbound SR-4 in Contra Costa County.
Part of this construction work entails adjustment of temporary bridge supports that span over SR-4. In order to ensure crew and public safety during this work, the contractor will close all lanes of SR-4 in the eastbound and westbound directions between the SR-4/SR-160 connector ramp and Laurel Road.
These closures are scheduled to take place on the evenings of February 25, 26, and 27th from 11:59pm to 5:00 am.
The detour for this work will be as follows:
- Eastbound motorist will be directed off the highway at the SR-160 off-ramp and redirected to return to eastbound SR-4 via the Laurel Road on-ramp.
- Westbound motorist will be directed off the highway at Laurel Road on-ramp and redirected to westbound SR-4 via the entrance of southbound SR-160.
Motorists are advised to expect delays and allow extra time for their commute. Please drive with caution through the detours and leave safe traveling distance between your vehicle and the vehicle ahead of you.
The California Department of Transportation (Caltrans) and the Contra Costa Transportation Authority (CCTA) are constructing two new connector ramps, one connecting westbound State Route (SR)-4 to northbound SR-160, and one connecting southbound SR- 160 to eastbound Highway 4 in Contra Costa County. This construction work will require a traffic shift on southbound SR-160, between Main St and westbound SR-4.
The traffic will transition from the currently traveled lane to a newly paved lane which begins near the Main St. on-ramp, which may cause an intermittent closure of the highway. The traffic shift will begin July 16, 2014, between 10 p.m. and 4 a.m. and may cause intermittant closure of the the highway. Read the full traffic advisory
Caltrans will close Lane #1 of SR-160 in Antioch, in the northbound direction between SR-4 and the 18th Street/Main Street off-ramp on Thursday evening, April 24, from 6:00 pm to 6:00 am. Calrtrans and the Contra Costa Transportation Authority (CCTA) are constructing two new connector ramps, one connecting westbound Highway 4 to northbound SR-160, and one connecting southbound SR-160 to eastbound Highway 4 as part of the Highway 4 improvements.
The Highway 4 projects include improvements that will help revitalize eastern Contra Costa County. The projects expand Highway 4 from four to eight lanes between Loveridge Road and SR-160, add two connector ramps between Highway 4 and Highway 160, and add a BART extension from Pittsburg to Antioch (eBART). This will greatly improve transit accessibility for the region and help reduce traffic congestion and enhance the quality of life for the more than 250,000 residents of eastern Contra Costa County. The projects have been carefully staged to keep 130,000 vehicles per day moving as major construction and demolition work continue, and include over *$1.3 billion in State, Federal, Contra Costa Measure C & J sales tax, regional bridge tolls, and other local funds.
Construction Starts on SR 160/HWY 4 Direct Connector Ramps
State Route 160/Highway 4 Direct Connector Ramps Project is anticipated to start on Monday, March 24, 2014 in eastern Contra Costa County. The project will construct two new connector ramps, one connecting westbound Highway 4 to northbound SR 160, and one connecting southbound SR 160 to eastbound Highway 4. The ramps will create a connection between the Antioch Bridge and Highway 4 and provide residents and motorists in eastern Contra Costa County with important improvements in safety and mobility.
Motorists are urged to use caution and slow down when entering the construction zone.
The first week in April, crews will conduct three to four days of installing cast-in-drilled-hole (CIDH) piles to support the connector ramps. (This process has been selected because it does not generate significant noise, and will minimize impacts to the surrounding communities.) Beginning in mid-April, construction hours will be extended to include two to three weeks of nighttime work to minimize daytime traffic impacts and maintain the project schedule.

PITTSBURG, CA – Congressman John Garamendi (D-Walnut Creek, CA), a member of the House Transportation and Infrastructure Committee, today issued the following statement after attending the groundbreaking for the Highway 4/Loveridge Road Widening Project:
“The Highway 4 Widening Project is a win, win, win for the Bay Area. It means thousands of new jobs, less congestion, and improved public transit access. Federal, state, and local government officials worked together to secure the necessary $165.4 million for this project.
“By widening a two mile stretch of highway between Antioch and Pittsburg riddled with congestion problems, we are creating 3,000 direct and indirect jobs and laying the groundwork for eBART to Antioch.
“In our present economy, smart investments in projects that create quality jobs and lasting infrastructure must be prioritized. The Highway 4 Widening Project lives up to that standard.”
The $165.4 million project is funded through a combination of federal, state, and local funds. This Project represents a cooperative effort among the California Department of Transportation (Caltrans), the Contra Costa Transportation Authority (CCTA), the Federal Highway Administration (FHWA) and the Bay Area Rapid Transit District (BART).
The Loveridge Road Widening Project involves widening to eight lanes approximately two miles of State Route from Pittsburg to Antioch. Each direction will have three mixed flow lanes and one High Occupancy Vehicle (HOV) from just west of the Loveridge Road Interchange to west of the Somersville Road Interchange. The new roadway will be concrete and will use 40,000 cubic yards of concrete. The project will consist of five new bridges, 12 new retaining walls, and five new signalized intersections, as well as the reconstruction of California Avenue and Loveridge Road.

Update: due to rainstorms, the construction of a carpool lane along Eastbound I-80 has been postponed three weeks from the original stated date.
Beginning April 26th, Caltrans will close the ramps between Highway 4 and Eastbound Interstate 80 in Hercules for six months.
Caltrans will shut down access from Highway 4 to Eastbound I-80 at 12:01 am on April 26th; traffic will be rerouted onto local streets. Drivers can use the Cummings Skyway or take Hercules to connect to Eastbound I-80.
The closure is for the addition of 4.7 miles of carpool lane on I-80 between Highway 4 and the Carquinez Bridge, with the intention of easing traffic jams in the long term.
The carpool lane extension will cost about $28.5 million, paid for by funds from the $1 Bay Area bridge toll increase approved by voters in 2004.
