Improvements are coming to Pace Street from 9th Avenue to 17th Avenue. This project will repair and widen the asphalt, make it easier to walk and bicycle and upgrade the street’s drainage system.
The project will add buffered bike lanes in both directions to give cyclists more space and improve safety. We will also install two rectangular rapid-flashing beacons (RRFBs) to help people cross the street more safely.
To improve drainage, we will upgrade the existing stormwater system. This may include adding new curb and gutter on the west side of Pace Street and making other drainage improvements needed.

This project aims to fix the roadway, widen the street and improve the drainage system along Pace Street from 9th Avenue to 17th Avenue. These upgrades will help traffic move more smoothly and make the street safer for everyone. Completing this work now costs less than waiting until the road becomes more damaged and requires reconstruction.

Project Map

The Street Fund Sales and Use Tax provides funding for a variety of City transportation services, programs, and improvements. The Street Fund Sales and Use tax is 3/4 of a cent, or less than one cent on a one-dollar purchase.
The City of Longmont’s Storm Drainage Fund is used for the maintenance, operation, and capital improvements of the city’s storm drainage system. It is funded by monthly user fees charged to residential and non-residential customers, as well as a 2022 storm drainage bond approved by voters.
This fund is used to pay for a portion of the capital costs for arterial street and intersection improvements needed due to new development in the city. It is established to ensure that new growth contributes to the infrastructure required to handle its impact on the transportation system. This fund receives revenue from payments of the Transportation Impact Fee on new construction.
