June 12, 2026

Construction is ongoing on the Bay Bridge Pump Station and Force Mains Replacement Project in the City of Newport Beach.

The first phase of construction replaces the dual force main system underneath and across the lower Newport Bay Channel. The force mains are two side-by-side sewer pipelines that are directly connected to the pump station.

Current Construction

Schedule Update: Extended work hours are expected to occur outside normal working hours starting Friday, June 12 and through the weekend. 

Location: Next to OC San’s existing Pump Station and heading eastbound towards Dover Drive

Crews have started microtunneling, a trenchless construction method that minimizes surface disruption by excavating underground.

  • When: May–July 2026
  • Work Hours: Monday–Saturday, 7:00 a.m.–7:00 p.m.
  • What to Expect:
    • Coast Highway open to traffic in both directions.
    • 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.

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

We are working closely with the City of Newport Beach and Caltrans to minimize impacts and appreciate the community’s patience as we perform this work. The safety of the public and our crews remain our top priority.

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.
