Overnight closure of I-25 near Larkspur for bridge work

July 16, 2021 - Central/Eastern Colorado

DOUGLAS COUNTY – A small segment of southbound Interstate 25 is closing for one-night next week to allow crews to set girders on the Upper Lake Gulch Bridge.

The closure, between Spruce Mountain Road (Exit 173) and Upper Lake Gulch Road (Exit 172), is from 8 p.m. Monday, July 19, to 5 a.m. Tuesday, July 20.  Additional closures include the northbound I-25 ramps at Upper Lake Gulch Road, the southbound I-25 off-ramp at Upper Lake Gulch Road and the Upper Lake Gulch Road underpass.

DETOURS: Southbound I-25 traffic will funnel into one lane just north of Spruce Mountain Road, where traffic will exit. Motorists then take Spruce Mountain Road and Upper Lake Gulch Road to the southbound I-25 on-ramp.

For access to Larkspur from northbound I-25, continue north on I-25, exit at the Sky View Lane/Tomah Road exit (Exit 174) and use the southbound I-25 off-ramp to Spruce Mountain Road.

A local detour is in place to access Lake Gulch Road.

Construction schedules are weather-dependent and could change. Current information is available on i25gap.codot.gov or by following the project on Facebook (@I25SouthGapProject). To receive text alerts, text I25GAP to 21000.

About the 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 $419 million project also includes shoulder widening, bridge reconstruction, new wildlife crossings, resurfacing with new pavement and modernizing technology. Project completion is scheduled for 2022.
