Construction Update:
Caltrans and the SBCOG appreciate the traveling public’s patience during construction, as major construction milestones took place in late 2024. Here is a short list of current construction updates:
- SR 156 continues to operate in one lane in each direction, during this phase in construction
- A new roundabout at Bixby Road is open, which also consists of one lane in each direction during this phase in construction.
- Union Road/Mitchell Road is fully reopened at SR 156 .
- The bypass exit from eastbound SR 156 to 4th Street/Business 156 reopened.
Drivers are reminded that SR 156 is still an active construction zone and encouraged to slow down and pay attention to temporary road signage and portable message signs alerting travelers of the upcoming traffic changes.
