Detour Map of Federal Boulevard Construction

Construction at the Federal and Bowles intersection is scheduled to begin Monday, June 1. Both the northbound and southbound lanes of Federal Boulevard will be closed at Bowles Avenue for most of June and July, and a detour will be in place.

Voters approved the TABOR override in 2017, providing $545,000 for upgrades to this busy intersection. This is enough funding to move forward with safety improvements, but not enough for the ultimate intersection changes.

The work will implement safety improvements for bicyclists, pedestrians and vehicular traffic. The Federal and Bowles intersection has the highest accident rate of any intersection in the city not involving Santa Fe Drive. This location has a history of accidents related to sight lines for drivers, pedestrians, and cyclists as well as having a mix of arterial streets and recreational trails. The location carries 46,000 vehicles daily and in the last five years, 108 accidents occurred including three involving bicycles and pedestrians.

Project Overview

Develop a vision for the future configuration of the intersection that addresses the needs of vehicles, pedestrians, bicyclists, and bus transit users; and to construct near-term safety enhancements compatible with the vision.

• Improve safety for bicyclists and pedestrians crossing the intersection, while maintaining adequate traffic operations.
• Analyze alternative improvements to the intersection that could be made in the future, when funding is available.
• Identify interim safety improvements that can be built as a first step toward the future intersection configuration.
