I-25 near 15th Street

Project Overview

In February 2012, the Colorado Department of Transportation (CDOT) began a safety and mobility improvement project on I-25 between approximately 20th Street and Speer Boulevard.  In addition, various vehicle, pedestrian and bicycle improvements will be made on Central Street, which the City and County of Denver is funding.  The $11.7 million project will continue through late 2013 or early 2014.

CDOT’s portion of the project will make the following improvements to I-25 and 15th Street:

• Adds auxiliary lanes on southbound I-25 from just south of 20th Street to just south of Speer Boulevard to help eliminate the weaving at the on and off-ramps along I-25.
• Replaces the 15th Street bridge over I-25 to accommodate auxiliary lanes on I-25, which allows for wider sidewalks on 15th Street.
• Reconfigures the I-25 HOV/tolled Express Lane exit to provide for a longer merge lane into mainline traffic
• Constructs sidewalk along Central Street between 15th Street and 16th Street, connecting to Denver’s portion of the project.

Denver’s portion of the project will make the following improvements to Central Street:

• Constructs a 10-foot bicycle/pedestrian path from 16th Street to 20th Street
• Adds additional on-street parking on the west side of Central Street north of the 17th Street curve
• Installs enhanced signage for the bike route connection at 20th Street
• Adds two-hour restricted parking signs along Central Street
