I-80 Westbound
Carquinez
(Al Zampa)
Bridge Deck
Rehabilitation
Solano/Contra Costa
Counties, Project 04-1Y700
Weekend Closure:
August 21 – 24, 2026
Project Location
This project is in Contra Costa
County and Solano County on
Westbound (WB) Interstate – 80.
Between East end of the
Carquinez Bridge (Al Zampa
Memorial) in Vallejo to the WB
Off-Ramp to Pomona Street in
Crockett.
Project Need
The Asphalt Concrete is
showing signs of aging and
deteriorating. Which results in
poor ride quality. To prevent
further wear and tear a repave
of the deck needs to be
completed.
Project Purpose
The purpose of the project is to
improve the rideability of the
deck surface, prolong the deck
service life, preserve the
structural integrity of the bridge,
and enhance safety for the
traveling public.
Project
Scope
• The top layer (1”) of the Asphalt Concrete will be replaced to improve rideability and preserve the structural integrity. • Bridge Deck Length: 3500 ft | Deck Width: 67 ft | 4 Lanes | • Anticipated Hot Mix Asphalt Tonnage: 1550 tons
Scheduled Closure
We will close I-80 for one weekend for the
worker safety and safety to the travelling
public and due to long curing times for full
concrete pavement replacement.
Westbound (53-hour weekend)
August 21, Friday (10:00pm) through
August 24, Monday (3:00am)
Need for Full Closure
Due to weather and temperature restrictions
• It is recommended that the work needs to be completed in August or September
• Paving works needs to be conducted in the Daytime from 10 AM to 5 PM
• Recommend work be down via a full weekend closure on
Westbound I-80 from Friday 10:00 PM to Monday 3:00
AM.
Benefits of a Full Weekend Closure of the Bridge
• For the safety of public and workers.
• Helps facility the need for overlap in waterproofing repair • Micro-milling and equipment cleaning before each pass • Meaning the paver can be cleaned at the end of
each pass to maintain material temperature
consistency
• Daytime weather is required for paving work due to its significant effect on the cooling of the custom thin
asphalt layer
