Newport Blvd Sewer Project

Newport Blvd. Ramp Closure

Post Date:11/06/2017

Since October, the temporary closure of the Newport Boulevard and Old Newport Boulevard transition ramp north of Coast Highway has been in place.  The closure is expected to last through the end of the year.   Dates and times are subject to change due to unforeseen operational factors or inclement weather. 

Over 20-feet deep pits are being excavated.  In the photo below, shoring plates were installed to provide support to the sides of the excavation.

Work Hours 

Construction hours are currently Monday through Friday, 8:30 a.m. - 3:30 p.m.  The ramp closure will remain in place 24 hours/7 days a week.  Dates and times are subject to change due to unforeseen operational factors or inclement weather. 

What to Expect

Increased construction noise and activity is expected.  Some parking spots may need to be taken from time to time.  Since traffic is being diverted to Hospital Road due to the ramp closure, some traffic congestion is expected.  Flaggers are in place at the Old Newport Boulevard, Hospital Road, and Westminster Avenue intersection to help with traffic flow during peak times. 

Construction activity is currently along northbound Newport Boulevard only.  There should be minimal impact to southbound Newport Boulevard.
