Photos: State Route 160/Highway 4 Connector Ramp Project

by ECT

On Friday, ECT visited the State Route 160/Highway 4 Connector Ramp Project with Ivan Ramirez, Engineering Manager for Contra Costa Transportation Authority.

According to Ramirez, a total of around 220 cement trucks will be needed when they begin to pour the concrete.

Although the project is currently slightly behind schedule due to environmental issues with birds laying nests, the project is still expected to be completed on time and under budget.

Here is more information on the project:

State Route 160/Highway 4 Direct Connector Ramps

The existing State Route 160/Highway 4 interchange currently includes only two of the four possible interchange movements: the eastbound Highway 4 to northbound State Route 160 connector ramp, and the southbound State Route 160 to westbound Highway 4 connector ramp. The State Route 160/Highway 4 Direct Connector Ramps project will construct two new connector ramps, one connecting westbound Highway 4 to northbound State Route 160, and one connecting southbound State Route 160 to eastbound Highway 4.

The project scope includes adding an additional 12-foot auxiliary lane to the outside of existing State Route 160 in both directions between the State Route 160/Highway 4 Interchange and the East 18th/Main Street Interchange, as well as building a soundwall extension and retaining walls. The southbound State Route 160/Highway 4 separation structure will accommodate a future eBART extension in the median of Highway 4.

PROJECT ALLOCATED BUDGET

The project is funded entirely by $50 million in Bridge Toll Funds.
