left turns at CO 119 and Hover Street in Longmont will close for construction starting in early September
To safely build the new southwest-bound bridge on Colorado Highway 119 at Hover Street in Longmont, all left turns at the intersection will be closed in early September and remain closed until the project is complete next year.
The right turn from southbound Hover Street to CO 119 will also be closed. All the closures will provide the construction team with a safe space to build the new vehicle bridge.
The basic concept of building a bridge over Hover Street for Boulder-bound traffic will make traffic more efficient by eliminating the need for a single sequence of traffic lights, increasing green light time for everyone. Additionally, grade-separating will improve safety and reduce traffic and pedestrian conflicts.
CDOT previously released a video explaining what is happening and why, and you can watch it on YouTube. (https://www.youtube.com/watch?v=8TjyJ367Mig)
All businesses will maintain access throughout construction.
