Commuters who drive Harbor Boulevard in Costa Mesa will have to find another route or risk being stuck in heavy rush-hour traffic beginning Monday morning.
The southbound lanes of Harbor between Wilson Street and Fair Drive will be closed for two weeks as construction crews continue work on a new storm drain, said Bob Brock, assistant city engineer.
The northbound lanes will be altered to accommodate part of the traffic, said Brock, but drivers should detour to Fairview Drive or Placentia Avenue. About 45,000 cars daily use that stretch of Harbor, which normally has three lanes for each direction of traffic.
The construction on the storm drain has already begun on the southern end of nearby Costa Mesa Golf Course. Brock said parts of the pipe will be installed in the next two weeks, as well as a structure to keep the pieces in place.
