Chain Stations Being Built Along I-70 Corridor/ Bridge Replacement Starts at I-25 and 128th Avenue

To help commercial vehicles    comply with Colorado’s chain law, new chain stations are being constructed along I-70 between Edwards and Golden.

Four Chain Stations Built Along I-70 Corridor

To help commercial vehicles comply with Colorado’s new chain law, new chain stations are being constructed along I-70 between Edwards and Golden. Just recently, the Colorado Department of Transportation completed construction on two new chain stations, one on westbound I-70 at 32nd Avenue and one at C-470.

Following the construction of the stations, CDOT will begin another project at the same locations to install signs with chain law information so drivers can plan ahead and chain up when necessary. 

In all, four new stations will be constructed along westbound I-70, and the two current stations will be expanded by adding 85 truck spaces. On eastbound I-70, four new stations will be added and one station will be expanded, adding 52 truck spaces for a total of 137 new truck spaces along the I-70 corridor.

Brannan Sand and Gravel Co. of Denver and DKS Enterprises Inc. of Brighton are the contractors for the two-phase project.

Bridge Replacement Starts at I-25 and 128th Avenue

The Colorado Department of Transportation began a bridge project in November at I-25 and 128th Avenue that will replace the existing 128th Avenue bridge over I-25 with one that is approximately 73 ft wide to accommodate two through-lanes in each direction as well as a 10-ft sidewalk on each side.

“Even though the new bridge will be able to accommodate two lanes in each direction, it will only be striped for one lane in each direction,” said CDOT Resident Engineer John Schwab. “When 128th Avenue is widened in the future, the bridge can then be striped for two through-lanes in each direction without additional work taking place on the bridge.”

The project began quickly, with crews completely closing 128th Avenue between Lincoln and Delaware streets. “The most efficient way for us to replace the bridge is to demolish it and construct a whole new structure,” added Schwab. “By proceeding in this manner, we will be able to construct the new bridge in seven to eight months, rather than a year or more, which will ultimately reduce the impacts to traffic.”

Jalisco International Inc. of Commerce City is the contractor for this $6.3-million project. The entire project will be complete by the end of June 2008.
