Traffic Alert: MacArthur to Close Monday for Roadwork

The section of northbound MacArthur Boulevard between Pacific Coast Highway and San Miguel Drive will be closed to traffic from 9 a.m. to 4 p.m., Monday through Friday, beginning October 21 and ending November 1. The lane closures are necessary to enable a contractor working for the City of Newport Beach to install a critical new water main and to relocate an existing vault located under the roadway.

Construction activity and the lane closures will only affect northbound (the inland direction) MacArthur Boulevard traffic. The southbound lanes along MacArthur Boulevard will remain open to traffic at all times.

Outside of the 9 a.m. to 4 p.m. full northbound closure hours, one northbound lane on MacArthur Boulevard will reopen to traffic.

The northbound MacArthur Boulevard lane closures are expected to create delays along Pacific Coast Highway in Corona del Mar, near Newport Center, and along alternative northbound routes such as Marguerite Avenue and Avocado Avenue. Motorists should avoid the immediate area, using alternatives such as Newport Coast Drive or Jamboree Road.

Transit service should not be affected significantly, as OCTA routes go along Avocado Avenue.

The contractor’s approved work hours extend beyond the full northbound lane closure hours, and motorists will see workers onsite prior to 9 a.m. and after 4 p.m. For safety purposes, motorists, cyclists and pedestrians are asked to please abide by all traffic control measures during the two-week period.

If inclement weather or unanticipated delays are encountered, the contractor may need additional working days to complete the project.

The work is part of Newport Beach’s $4.5-million, Corona del Mar Water Transmission Main project which will improve water supply to the Corona del Mar section of Newport Beach.
