Newport Blvd Sewer Project

Ramp Closure on Newport Blvd. near PCH Starts in October

Post Date:09/27/2017

Updated 10/2/17:  There will be night work Monday, October 2, 9 p.m. - 6 a.m.  The contractor will be setting up k-rail, or traffic control barriers, to close the northbound Newport Boulevard and Old Newport Boulevard transition ramp.   

Starting the first week of October, there will be a temporary closure of the Newport Boulevard and Old Newport Boulevard transition ramp north of Coast Highway for approximately 3 months.  The closure is needed in order to excavate and construct new sewer pipe along Newport Boulevard for the regional sewer system.  This will reduce the number of northbound Newport Boulevard lanes.  See maps below for the ramp closure location and suggested detour map.

The Newport Blvd. District 6 Trunk Sewer Relief construction project will replace an existing 60 year old regional sewer pipeline with a larger sewer pipeline to increase the sewer flow capacity and reduce the risk of spills.  Construction will take place along Newport Blvd. between Pacific Coast Highway and Industrial Way in the City of Newport Beach and Pomona Ave and 17th St in the City of Costa Mesa.
