The Avila Beach Drive Bridge Seismic Retrofit Project is located at the crossing just west of the town of Avila Beach where Avila Beach Drive crosses over San Luis Obispo Creek. The existing bridge was built in 1967 to provide the only public access road to Port San Luis and Diablo Canyon Power Plant.
The Bridge is subject to collapse during an earthquake and the seismic retrofit will assure an evacuation route and will upgrade the bridge to current codes.

Souza Construction will be finishing their work under the bridge this week and next week in between rain storms. Next week -- the week of December 10 -- Souza will begin work up on the roadway approaches and on the bridge. Work in the roadway will occur only during off-peak hours with only single-lane closures anticipating maximum 10-minute delays. Bicycle and pedestrian traffic will be maintained at all times during construction.

Throughout the month of September Souza Construction has been working under the bridge placing the formwork and rebar for the Corbels. The Corbels are Seismic Retrofit features that will be placed at the top of each bridge pier to help more securely attach the piers to the bridge deck.
Souza will also continue to work on Pier 3. Pier 3 is one of the two piers in the creek channel that is in need of maintenance due to its location in the creek. They have stripped the bad, delaminated concrete from that pier and will be placing a new concrete pierwall jacket to protect the pier from further degradation and from creek and ocean scour.
During the month of October, Souza will continue working under the bridge and will only occasionally close lanes on the bridge to pour concrete (single lane closures only). Souza Construction currently anticipates that they will be working on top of the bridge starting in the first week of November. When work begins on top of the bridge, the public can expect single lane closures more often.

Chevron Environmental Management has finished the removal of their 5 abandoned pipes from the underside of the bridge and they are currently in the process of moving off the site.
Souza Construction has begun work including:
- Work below and around Abutment 1, which is the abutment on the west (Port San Luis Harbor) side,
- Excavation around Pier 3 and removal of the old pierwall jacket to prepare for its replacement - this will first require them to construct shoring by installing a steel plate cofferdam around Pier 3, and
- Erected scaffolding under the bridge at Piers 4 and 5 to begin work on the seismic retrofit features that will strengthening the connect between bridge deck spans and the piers.
