Projects in Planning and Design
Boulder County Transportation in partnership with the City of Longmont is planning to reconstruct both Sunset Street and Boston Street in a section of unincorporated Boulder County located within Longmont.
Examining Ken Pratt, Hover, and Nelson, this study will identify needed improvements for cars, bikes and pedestrians.
Projects Under Construction
The bridge is approaching the end of its useful life. It is too narrow for the traffic volumes that cross it daily, classifying it as “functionally obsolete” per the Colorado Department of Transportation's biannual bridge reports.
The City’s annual Pavement Management Program contracts with private sector contractors for replacement of broken curbs and sidewalks, preventive maintenance such as crack sealing, chip sealing and pavement overlay and reconstruction.
Projects Recently Completed
This project included the design and construction of a new roadway from Main Street (US 287) eastward connecting to Martin Street.
Construction focused on the alleys, breezeways and parking lots to further support the growth and development of downtown Longmont.
"Focus on South Main" was a multi-year effort intended to improve the southeastern gateway to Longmont’s core along Main Street. There were three components that comprised the Focus on South Main effort: Main Street and Ken Pratt Boulevard Intersection Improvements, Main Street Bridge Replacement at St. Vrain Creek, and Main Street Pavement Reconstruction.
This project provided two, new pedestrian/bicycle connections:
- between Dry Creek Drive and Pike Road
- at Hover Street and Dry Creek
