I-25 full closure at Sky View Lane Bridge near Larkspur weekend of Jan. 11

Travel Advisory

January 6, 2019 - Metro Denver Area, Colorado/Southeastern Colorado - Traffic to go around work using ramps, expect delays

Larkspur - As part of the Interstate 25 South Gap project to improve safety and travel reliability, crews will begin drainage improvements at the Sky View Lane Bridge (Tomah Rd.) over I-25. These improvements are part of CDOT’s Whole System – Whole Safety program.

To safely perform drainage work, crews will close I-25 under the Sky View Lane Bridge for 16 hours on January 11 and 12 and detour all I-25 motorists using the Sky View Lane on- and off-ramps. Motorists can expect to add up to 45 minutes to their trip during peak travel times. 

Traffic Impacts

7 p.m. Saturday, Jan. 11, to 11 a.m. Sunday, Jan. 12.- Traffic on northbound I-25 will be taken off the mainline interstate and shifted to one lane through the northbound Sky View Lane ramp.  The same will occur on the southbound side. Traffic on southbound I-25 will be shifted to one lane through the southbound Sky View Lane ramp. All traffic will be shifted around the construction and return back to the open lanes on I-25.  *See maps at end of release. 

During this drainage work, crews will remove asphalt and install two drainage pipes under northbound I-25 lanes and one pipe under southbound I-25 lanes. Following this work, crews will replace the asphalt they removed and restore traffic to its original configuration.

All construction schedules are weather-dependent and subject to change.

About the South Gap Project

CDOT is improving 18 miles of I-25 between Monument and Castle Rock by widening the highway from two to three lanes in each direction. The new lane will operate as an Express Lane, allowing motorists the choice of taking the Express Lane for a faster, more reliable travel time in exchange for a toll. Express Lanes will be free to vehicles with three or more people and motorcycles. All travelers will have the choice of taking the general-purpose lanes for free.

The $350 million project also includes shoulder widening, rebuilding bridges, new wildlife crossings, resurfacing with new pavement and modernizing technology. Project completion will occur in 2022.

Travel options to improve commutes are available during construction. Some of the services include a new Bustang route from Colorado Springs to the Denver Tech Center. CDOT is partnering with the Denver Regional Council of Governments' Way to Go program to provide more commuting options, such as incentives to vanpool and carpool. Visit i25myway.org to learn more.

Whole System - Whole Safety  

In early 2019, CDOT announced its Whole System. Whole Safety initiative to heighten safety awareness. This initiative takes a systematic, statewide approach to safety combining the benefits of CDOT’s programs that address driving behaviors, our built environment and the organization's operations. The goal is to improve the safety of Colorado’s transportation network by reducing the rate and severity of crashes and improving the safety of all transportation modes. The program has one simple mission – to get everyone home safely.
