ANTIOCH -- Motorists driving through a retail-heavy stretch of Lone Tree Way near the Highway 4 bypass should expect delays the next few weeks as work starts to expand the freeway to four lanes.
Work to build a new undercrossing at Lone Tree starts Monday. Construction crews will be pile driving from 7 a.m. to 5:30 p.m. on weekdays the next four to six weeks, according to a Contra Costa Transportation Authority news release.
Local residents and businesses can expect increased background noise during pile driving, according to the transportation authority.
Meanwhile, work continues elsewhere on the bypass.
Drivers can expect delays next week, when traffic will be restricted to one lane as the project contractor adds temporary striping and other traffic-control devices between Lone Tree Way and Balfour Road.
The one-way traffic will be from 10 p.m. Saturday to 7 a.m. Sunday, 10 p.m. Sunday to 4 a.m. Monday, and from 8 p.m. to 6 a.m. Monday through Friday.
The contractor will be performing one-way traffic control and flagging operations, officials said. Motorists are advised to expect some delays and allow extra time for their commute.
The $32 million project, which is expected to be completed by spring 2014, will widen the highway from two to four lanes from Sand Creek to Laurel Road in Oakley.
