CDOT Press Release

This week, the Colorado Department of Transportation will install girders for the northern portion of the new 104th Avenue bridge over I-25. The work will require a full closure of northbound and southbound I-25 on Monday, October 19th and Tuesday, October 20th.

Below is the lane closure schedule for Monday, October 19th through Thursday, October 22nd. All work is weather permitting.

Monday, October 19th and Tuesday, October 20th – One lane of northbound and southbound I-25 near 104th Avenue will be closed at 7 p.m. with all lanes closing at 9 p.m. for girder installation. All lanes of northbound and southbound I-25 will reopen by 5:30 a.m. the following day. Motorists will be detoured via the on and off-ramps at 104th Avenue. In addition, the right lane of westbound 104th Avenue over I-25 will be closed from 8:30 p.m. to 5:30 a.m.

Wednesday, October 21st and Thursday, October 22nd – One lane of northbound and southbound I-25 near 104th Avenue will be closed at 8 p.m. with a second lane closing at 10 p.m. for bridge work. All lanes of I-25 will reopen by 5:30 a.m. the following day.

Major delays are expected throughout the week and alternate routes are strongly advised. CDOT would like to remind motorists to obey all traffic signs and flaggers and to “Slow for the Cone Zone.”

The existing 104th Avenue bridge over I-25 was originally constructed in 1962 and is one of Colorado’s structurally deficient bridges. When complete, the new bridge will accommodate an additional left turn lane from eastbound 104th Avenue to northbound I-25.

Hamon Contractors, Inc. is the contractor for this $6.5 million project scheduled to be complete by the end of September 2010. CDOT is funding the bridge replacement and the Northglenn Urban Renewal Authority (NURA) is funding the aesthetic improvements which will include upgraded bridge rail and upgraded bridge lighting similar to the existing lighting on the 112th Avenue overpass bridge. Aesthetic improvements also include cornerstone monuments at the four ends of the bridge and “Northglenn” monument signage mounted to an upgraded retaining wall.
