Traffic lanes are being shifted on Interstate 80 in Alameda and Contra Costa counties to accommodate initial construction for the Integrated Corridor Mobility project.

Lanes have been re-striped and mobile information signs put in place to warn drivers of the shift to the right at several locations on the Eastshore Freeway between Powell Street in Emeryville and Potrero Avenue in El Cerrito, Caltrans announced this week.

The realignment is needed to create space for foundation work along the median that will allow installation next year of electronic information signs that are a cornerstone of the project.

Similar work will be done at locations along I-80 between Emeryville and Crockett.

Upcoming work will include closure of the Ashby and University Avenue onramps from 9 p.m. to 5 a.m. Sept. 24.

Caltrans reminds drivers to slow down in construction zones.

The Integrated Corridor Mobility project is intended to improve safety and vehicle flow on the congested I-80 corridor using automated, integrated technology to manage traffic and provide motorists with real-time information.
