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.

Current Travel Impacts

Traffic signals with pedestrian indicators have been powered on at the following intersections:

• Ohio and Broadway
•  Walsh and Broadway
•  Ohio and Lincoln

 

Impacts:

• Drivers are now able to turn left from southbound Broadway onto Ohio, with access to Lincoln and the northbound I-25 on-ramp.
•  Drivers are now able to travel east and west on Ohio between Broadway and Lincoln.
•  Drivers are now able to turn left from northbound Broadway at Ohio, onto the elevated southbound I-25 on-ramp.
•  Drivers are now able to turn left onto westbound Ohio from the northbound I-25 off-ramp.
•  Drivers accessing the 800 block of S. Lincoln are now able to enter the block on Lincoln and exit onto Ohio via the alley. One way traffic is allowed.

Please see the current pedestrian access map linked here for details.

Please note that there will be variable traffic patterns along Broadway for the duration of this project. All lane closures will be communicated in advance.

All project activities are weather- and site-condition-dependent, and schedules are subject to change.

Current Access to Southbound and Northbound I-25

Accessing the southbound I-25 on ramp: Drivers going south on Broadway will now turn right to access the I-25 southbound on-ramp at Ohio Avenue. Drivers are now able to turn left from northbound Broadway at Ohio, onto the elevated southbound I-25 on-ramp.

Accessing the northbound I-25 on-ramp: Northbound I-25 access remains at Lincoln for drivers on northbound Broadway. Drivers are now able to turn left from southbound Broadway onto Ohio, with access to Lincoln and the northbound I-25 on-ramp.

Project Schedule

Construction began in summer 2023, with completion expected in spring 2026. Crews will be on-site between 7:00 a.m. and 5:00 p.m., Monday–Friday, with occasional weekend work to lessen travel impacts. Sidewalk and roadway impacts will be communicated weekly – to sign up for these weekly updates, please email the project team at i25broadwayinterchange@gmail.com.

Completed Milestones

Since the project began in Summer 2023, the project has:

• Opened new elevated on-ramp to southbound I-25 from Broadway.
• Extended Bannock Road south of Exposition Avenue, providing access to the RTD Park-n-Ride from the north. This includes: improved lighting, landscaping and a new multi-use pathway. 
• Completed sanitary sewer and storm sewer work throughout the area.
• Constructed a major portion of the elevated on-ramp to southbound I-25 , including two new bridges.
• Constructed a temporary parking lot, W. Exposition from Broadway to Bannock and elevated I-25 on-ramp across Broadway.
• Reconstructed E. Exposition from Broadway to Lincoln and installed new traffic signals at both intersections.
• Reconstructed east sidewalk between Ohio and Kentucky.
• Reconstruct Kentucky Avenue, combining the existing intersection with the elevated southbound on-ramp to I-25.
• Install new traffic signals at Ohio Avenue (between Broadway and Lincoln Street) and at Broadway and Kentucky Avenue.
• Reconstruct local streets including Lincoln, Broadway, Kentucky and Ohio
• Connect the Broadway bike lane to the RTD Broadway station.
• Extend bikeway from Center to Exposition.

By Spring 2026, this project will:

• Expand multi-use pathways for pedestrians and cyclists.

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.

Striping has been added to the northbound I-25 off-ramp lanes with access to Lincoln, Ohio and Broadway. Image taken facing east on northbound I-25 off-ramp, south of Ohio.

Crews finalize installing signage ahead of traffic signals and pedestrian indicators being turned on. Image taken facing northeast at northbound Broadway at Ohio intersection.

Striping has been added to the RTD parking lot beneath the I-25 viaduct. Image taken facing northwest under the I-25 viaduct, west of Broadway.

A raised pedestrian crossing has been added to increase safety of pedestrians traveling on Ohio. Image taken facing north from the right lane of the northbound I-25 off-ramp at Ohio.

Progress continues to be made at the Denver Tramway Trolley Line interpretative mitigation area. Image taken facing east from the sidewalk east of Bannock and north of the I-25 on-ramp
