Boulder County Transportation, in partnership with the Colorado Department of Transportation, is planning to reconstruct the intersection
of US 287 and Isabelle Road. Construction is currently anticipated for 2021.
- Widening of Isabelle Road from 109th Street (Town of Erie) to 800 feet west of US 287.
- Stripe new buffered bike lanes both east and west on Isabelle Road across the intersection
- Lengthen the existing turn lanes on Isabelle Road to reduce conflicts for waiting vehicles
- Add dual left-turn lanes for westbound traffic
- Replace existing traffic signals with new poles on raised islands
- Add pedestrian crossings on all four corners
- Install new street lights to improve visiability
- Realign the Isabelle Road and 109th Street intersection to improve sight distance for both southbound and westbound traffic
- Construct new wetlands northeast of the intersection to mitigate project impacts and improve habitat
- View preliminary design exhibits
There are no public meetings scheduled at this time.
