Traffic Impact

I​ntermittent shoulder and lane closures as needed. 

Construction Impacts

Some work can be done during the day, but we will also be working at night. 

The project is estimated to complete in 2022.

Construction Activities

We are removing and replacing signal equipment.

​Pedestrians, including those with disabilities, will have access through or around work zones. 



Enlarged project mapMission Street has seven signalized intersections that are historical high crash locations for Region 2. Most of the crashes are due to congestion. Our goal with this project is to reduce some congestion by using newer signal timing technology.

In order to improve the flow of traffic on Mission Street, are replacing any damaged traffic signal sensors, as well as installing:  

  • New traffic controllers.

  • Traffic detectors.

  • Technology that works with traffic conditions and signals to keep traffic moving smoothly.

This technology will adjust when a green light starts and ends to follow the current traffic pattern. These improvements help manage congestion, as this technology automatically adapts to unexpected changes in traffic conditions and improves travel time reliability.​

The installation of the new equipment will occur at night and should have minimal impacts to traffic flow. If lane closures are needed, the work zone will be controlled by flaggers.
