Tefft Street at Highway 101 Interchange
Reconfiguration the US 101 and Tefft Street Interchange to reduce delay on Tefft Street.
Significant congestion on Tefft Street at the US 101 interchange is an ongoing problem. Especially apparent during peak hours, drivers on Tefft Street may wait through multiple signal changes. To reduce this congestion and maximize efficiency, the project will increase the traffic signal “green time” on Tefft Street by making the following improvements (as shown below):
- Restrict left turn movements from Frontage Road onto Tefft Street
- Widen the north and south bound offramps to allow the same number of cars to exit US 101 within a shorter "green time"
- Re-synchronize the traffic signals to transfer "green time" from the offramps to Tefft Street
Estimated Construction Cost: $2.1 million
