Sterling Construction Company, Inc. Joint Venture is Selected as the Top Ranked Firm for a California Department of Transportation Project

Sterling Construction Company, Inc. (NasdaqGS:STRL) (“Sterling” or “the Company”) today announced that its affiliate, Myers & Sons Construction (“Myers”), was selected as the top ranked firm on the Interstate 215 Barton Road Interchange Reconstruction Project in a 50/50 joint venture with Steve P. Rados, Inc. (“Rados”). The project will be constructed utilizing a Construction Manager/General Contractor (CMGC) delivery method for the California Department of Transportation (Caltrans), in cooperation with the San Bernardino Associated Governments (SANBAG), the City of Grand Terrace, and the City of Colton. The programmed funds for the project total $36.0 million and Caltrans intends to negotiate with the top ranked firm to establish a final construction price. Construction is expected to begin in early 2016 and be completed by mid-2018.

According to the Request for Qualifications, “The objective of the project is to address the operational deficiencies of traffic congestion, limited capacity, and inefficient traffic operations at the existing I-215/Barton Road interchange. Limited work spaces within the interchange footprint require development of optimal construction staging strategies. The CMGC’s suggestions on work zone traffic control plans and construction material staging areas are expected to help optimize staging strategies.”

Peter MacKenna, Sterling’s Chief Executive Officer, commented, “We’re very pleased to have been chosen to construct this interchange with our joint venture partner. This project adds to our growing backlog of significant transportation projects in the California marketplace and furthers Myers and Sons Construction position as a leader in CMGC construction."
