Authorities started a street-widening project by closing part of Harbor Boulevard on Monday, according to a news release.
The outermost lane of northbound Harbor from south of Adams Avenue to north of Ponderosa Street will be closed for two weeks, the release said.
During the closure, the city will add a third eastbound left-turn lane, a second southbound right-turn lane and longer northbound left-turn lanes, said Raja Sethuraman, the city's transportation services manager.
The project is expected to cost $2.8 million and will be covered by Measure M transportation funds, Sethuraman said.
Southern California Edison will also be replacing a utility vault during this time. The lane is expected to reopen Feb. 28.
To ease traffic congestion, the city is altering the traffic signal timing at the Harbor and Adams to allow more cars to move through the area. Motorists should still expect delays during the closure, the release stated.
