CDOT Press Release

Last week, the Colorado Department of Transportation (CDOT) completed the first phase of the bridge replacement project at I-25 and 104th Avenue. With the northern portion of the new bridge now complete, westbound 104th Avenue has been realigned to the north and construction is starting on the center portion of the new bridge this week with bridge demolition.

“A third of the new bridge is now complete so it is time to demolish the center portion of the existing bridge and construct the center portion of the new bridge,” said CDOT Resident Engineer John Schwab. “To complete the bridge demolition, we will completely close I-25 near 104th Avenue over the next three nights. We strongly encourage motorists to seek alternate routes as there will be major delays.”

The bridge demolition will take place Tuesday, January 5th through Thursday, January 7th. Each night, all lanes of northbound and southbound I-25 near 104th Avenue will be closed at 9 p.m. and will reopen by 5:30 a.m. the following day. During the full closure of I-25, motorists will be detoured via the on and off ramps at 104th Avenue. No left turns onto 104th Avenue will be allowed during the closure. Uniformed traffic control will be used to direct motorists through the interchange.

Major delays are expected 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.
