CLAYTON -- Starting next week, motorists headed between east and central Contra Costa on a popular two-lane road shortcut near Mount Diablo may want to add a few minutes to their travel time.

Work is set to begin next week on a Marsh Creek Road bridge to construct a new soldier pile with precast concrete lagging on one side of the culvert, and reinforcing the existing side with soil nails, according to a Contra Costa public works news release.

The bridge is located on Marsh Creek near Gill Drive, about three miles east of Morgan Territory Road and about six miles from Clayton.

The project will include installation of temporary creek dividers and rock slope erosion control materials. Construction will require traffic delays and single lane closures weekdays after 9 a.m., according to the county. Work is expected to take 10 weeks, barring any unforeseen circumstances.
