Travel and Safety Improvements at Broadway & I-25

Project Summary

DOTI is making travel and safety improvements at Broadway & I-25 that include replacing the existing at-grade southbound on-ramp to I-25 from Broadway with an elevated ramp to ease vehicle congestion and enhance safety. Other work will improve access to the I-25 & Broadway Station for people who walk and bike.

This project will:

  • Replace the existing at-grade southbound on-ramp to I-25 from Broadway with an elevated ramp
  • Build a new stretch of Bannock St south of Exposition, creating a new entrance to the RTD Park-n-Ride from the north side
  • Reconstruct local streets including Lincoln, Broadway, Kentucky and Ohio to improve traffic flow, while maintaining the south side entrance to the RTD Park-n-Ride at Kentucky Avenue
  • Extend the bikeway currently being constructed on Broadway to complete access to the station by bike
  • Install new traffic signals on Ohio between Broadway and Lincoln and at Broadway and Kentucky
  • Expand multi-use pathways along Lincoln, Broadway, Kentucky and Ohio for walking and biking

The I-25 & Broadway Station is the second busiest in the RTD system and supports a high frequency of bus travel along the Broadway corridor, connecting Englewood to downtown Denver.

Project Updates and Schedule

Construction began summer 2023, with completion expected in 2025. Crews will be on-site between 7:00 a.m. and 5:00 p.m., Monday-Friday, with occasional weekend and overnight work to lessen travel impacts. Sidewalk and roadway impacts will be communicated weekly.

During construction, motorists, pedestrians and bicyclists are encouraged to plan routes – following detours and signage – and exercise caution while traveling in and around the construction zone.
