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 Road) over Interstate 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 Saturday and Sunday 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.

Here are the traffic impacts:


7 p.m. Saturday to 11 a.m. Sunday: 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.

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.
