At the Bay Bridge Pump Station site, excavation includes using a deep soil mixing drill rig.

While most activity has been taking place near the existing Bay Bridge Pump Station site, activity is ramping up across the bay. Crews are working on a deep excavation as part of the new sewer force mains replacement.

Locations:

  1. Next to OC San’s Pump Station
  2. Shoulder of Eastbound Coast Highway past Dover Drive

When: Ongoing–Spring 2026*

Hours: Monday–Friday, 7 a.m.–5 p.m.*

What to Expect:

  • Coast Highway will stay open to traffic in both directions.
  • Sidewalk closures near the work zone.
  • Increased activity, dust, and noise near the work areas during construction.
  • To minimize traffic impacts on Coast Highway, some activities may need to occur outside normal working hours.

Specific to Coast Highway and Dover Drive Location:

  • K-rail will be in place, temporarily closing the bus stop turnout. OCTA Stop 4933, Routes 1 & 55, are closed until further notice. Use the prior or next bus stop. Visit OCTA for more information.
  • Crossing path under Coast Highway is closed. Please take the appropriate detours.
  • Sound panels will be placed by the nearest neighbors to mitigate noise.

We appreciate your patience as we construct this important infrastructure upgrade. Your safety, and the safety of our crews, is our top priority.

*All dates and times are subject to change due to operational factors or inclement weather.

Project Description

This project will replace the existing Bay Bridge Pump Station located on Coast Highway between the Bay Bridge (east of Dover Drive) and Bayside Drive in the City of Newport Beach. The project will also replace the pressurized pipes, also referred to as force mains, consisting of two parallel pipelines which carry wastewater across the lower Newport Bay Channel. Wastewater then makes it way to OC San’s Reclamation Plant No. 2 in Huntington Beach.

Project Background

The Bay Bridge Pump Station was originally constructed in 1966 and is over 50 years old. The force mains are also over 50 years old. These critical assets are reaching the end of their useful life and need to be replaced to ensure they are reliable for the next 50 years. The new facility will be built to current structural and safety codes, making it safe and reliable to workers and the public.

The Bay Bridge Pump Station and Force Mains are located near pristine beaches along the Newport Channel Bay and is surrounded by residents, businesses, and visitors throughout the world. This pump station system transports between 4 to 18 million gallons of wastewater every day from the Newport Beach community. This project is needed to ensure we continue to collect, transport, and recycle Newport Beach’s wastewater safely while protecting the public health and the environment.

More information about the project can be found in the FAQ section.
