Aug. 27, 2026 - Northeastern Colorado - Check video and map detours to find out how to get around for the next year as new bridge is built to improve safety and efficiency

Longmont - In order 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 of the closures will give the construction team safe space to build the new bridge for vehicles.

“Building a bridge in the middle of the busiest intersection in Longmont while also maintaining all business access isn’t going to be easy,” said Colorado Department of Transportation Regional Transportation Director Heather Paddock. “But by closing some turns and everyone planning their trips thoughtfully, construction will be completed quicker, construction for workers and the public will be safer and it will reduce overall impacts to businesses and the travelling public.”

The basic concept of building a bridge to go over Hover Street for Boulder-bound traffic will make it more efficient for traffic as there will be one entire sequence of traffic lights that won’t be needed, increasing green light time for everyone. Additionally, grade separating will improve safety and reduce traffic and pedestrian conflicts. CDOT previously released a video about what and why this is happening and you can watch it on YouTube.

All businesses will maintain access throughout construction.

The only access that will be closed until the project is complete is a right-in access to PNC Bank. The bank and other businesses nearby are still accessible from the many other entries from CO 119 and Hover Street to the mall area.

In early July, prep work began at the intersection with the removal of one of the left turn lanes from CO 119 to Hover Street and placement of some temporary signals and temporary pavement for the upcoming traffic shift. As soon as the beginning of September, things are going to be changing and staying that way for about a year.

To allow the construction team to have room to build the bridge and all the other pieces that will tie-in to it, drivers will no longer be able to left at the Colorado 119 and Hover intersection. Most of the right turns will still be open. Through-traffic will proceed as it does today.

Here are a few ways to get around without making those turns (you can also watch a short video on the detours)

Hover Street to Boulder-bound CO 119

This is the one right turn from southbound Hover Street to CO 119 that will be closed for the next year. But you have some choices:

  • You can go west on Clover Basin Drive and then south on Airport Road to CO 119
  • Or, you can continue through the intersection south on Hover which turns into 95th Avenue until you get to Colorado Highway 52 and go west to CO 119
