This project will improve conditions by replacing the currently undersized sewer pipe

ATASCADERO — The City of Atascadero is currently in construction on the Traffic Way Sewer Improvements Project. This project replaces approximately one mile of undersized sewer main beneath Traffic Way, between San Jacinto Avenue and Bajada Avenue. 

Work in the Community Center Parking Lot is continuing and is anticipated to be completed before the end of the year. Beginning the week of Dec. 20, sewer main replacement will begin on Traffic Way, progressing from Bajada Avenue north to San Jacinto Avenue. During construction, the contractor will be required to keep open at least one lane, with flagging control for traffic, as well as access to adjacent residences and businesses. However, for residents and others traveling on Traffic Way, delays should be expected. Parents are encouraged to allow for extra time during school drop-offs and pickups or use alternate routes other than Traffic Way. Work on Traffic Way is expected to take approximately three months but will be contingent upon weather conditions. The City of Atascadero apologizes for the inconvenience but appreciates everyone’s patience and understanding as the City completes this badly needed sewer upgrade.

When possible, the contractor will maintain two-way traffic on Traffic Way. However, this will require restricting curbside parking at times along lengths of Traffic Way to allow traffic to shift. 


This project will improve conditions by replacing the currently undersized sewer pipe, and will also include replacement of sewer manholes, reconnection of 55 private sewer laterals to the new main, and repaving the half-width of Traffic Way over the new sewer main.
