Ralph L Wadsworth (RLW) and SEMA Construction have secured a contract to design and reconstruct a section of Interstate 25 (I-25) in the Weld and Larimer counties of Colorado, US.

Under the contract, awarded by the Colorado Department of Transportation (CDOT), the joint venture (JV) partners will be responsible for widening the portion of I-25 between SH-66 and the SH-402 Interchange.

Work is likely to start in mid-2019, once the design has been finalised and the construction manager / general contractor (CMGC) contract is selected.

Sterling Construction Company’s subsidiary RLW and SEMA will be responsible for widening the highway from two lanes in each direction to accommodate two more general purpose lanes and an express lane both ways.

The contract also includes reconstructing all interchanges within the project limits, including replacing existing bridges.

“Colorado is an important part of our strategic growth plans throughout the Rocky Mountain region for our heavy civil construction business.”

Sterling Construction Company CEO Joe Cutillo said: “The selection of our joint venture with SEMA by CDOT for this major highway project is representative of our strategy to pursue heavy highway awards where we can deliver greater value to the project owner through our extensive design-build capabilities.

“Mead and its surrounding communities comprise a rapidly growing suburb within the greater-Denver area and there is a pressing need to accommodate increasing vehicular traffic as well as enhance various multi-modal connections.

“Colorado is an important part of our strategic growth plans throughout the Rocky Mountain region for our heavy civil construction business, and we are very excited about this and other upcoming opportunities.”

In August 2016, RLW won a $21.5m contract from CDOT to reconstruct the Crossroads Bridge on I-25 in Larimer County, Colorado.

Sterling Construction Company provides construction services in Arizona, California, Colorado, Hawaii, Nevada, Texas, and Utah, among other US states.
