Document Description
The City of Arroyo Grande (City) proposes to replace the existing Arroyo Grande Creek Bridge 49C-0380 at Traffic Way (Traffic Way bridge). Traffic Way follows a north–south corridor approximately 0.1 mile east of U.S. Highway (US) 101 in the city of Arroyo Grande, San Luis Obispo County, California. Traffic Way bridge provides vehicular access over Arroyo Grande Creek, which runs through the city of Arroyo Grande parallel to State Route (SR) 227. The surrounding land is generally level and is primarily comprised of an urbanized business district. The existing bridge is hydraulically inadequate as it is subject to creek bed degradation and prone to scour issues. The existing piers and abutments have experienced scour issues for the past several years, making this bridge “scour critical” and in need of replacement. The changes in the creek have exposed the embedment of the supporting piles and the risk level for further damage to the bridge is high. The purpose of the project is to replace the scour critical bridge, improve public safety, stabilize Arroyo Grande Creek, and reduce future maintenance costs. If the bridge is not replaced, the condition will continue to deteriorate and eventually bridge closure will be required.
