Sterling Construction Company, Inc. (NasdaqGS: STRL) (“Sterling” or “the Company”) today announced that a joint venture between Sterling’s subsidiary, Ralph L. Wadsworth Construction Company, LLC (“RLW”/51% interest) and SEMA, Inc. (“SEMA”/49% interest), have been selected by the Colorado Department of Transportation (“CDOT”) to design and perform rehabilitation work on Colorado’s I-25 from SH66 to SH402.  The design finalization and execution of the project is estimated to approximate $35.7 million with Sterling’s portion approximating $18 million.  The project commenced in December 2020 and is expected to be completed in the second quarter of 2023.

This project consists of the replacement/widening of 12 bridges, with full interchange construction at LCR16, SH60, and SH56. Additional scope elements include early embankment and grading at the bridge locations, constructing the extension of eight irrigation crossings, drainage, and fiber optic relocation. Future packages consist of heavy utility relocation and the reconstruction of two general purpose lanes, one express lane, a painted buffer and shoulders in each direction for 12 miles of I-25.

Joe Cutillo, Sterling’s CEO commented, “We’re pleased that CDOT has selected our joint venture with SEMA to continue the work we began in mid-2019 on the improvement of the I-25 corridor between Denver and Fort Collins.  This stretch of highway runs through a rapidly growing suburb within the greater-Denver area where the need to accommodate a higher volume of vehicular traffic becomes more critical to safety and congestion mitigation every year.  Colorado is a critical element of our strategy to grow in the Rocky Mountain region, where we have been increasingly successful in winning heavy highway awards and can deliver value to our customers throughout our extensive design-build capabilities.”
