Sterling Awarded a Utah Department of Transportation Highway Contract Valued at Approximately $23 Million

THE WOODLANDS, Texas–(BUSINESS WIRE)–Sterling Construction Company, Inc. (NasdaqGS: STRL) (“Sterling” or “the
Company”) today announced that its subsidiary, Ralph L. Wadsworth
Construction Company, LLC (“RLW”) has been selected by the Utah
Department of Transportation (“UDOT”) to perform construction work in
the area of Exit 16 on I-15 in Washington County, UT near Zion National
Park. The $23 million job is expected to be completed late this year.

The project will be executed in several phases in order to minimize its
impact on traffic, given the heavy utilization of this I-15 interchange.
Key elements of the job will include the excavation of approximately
200,000 cubic yards of soil and rock and laying 70,000 tons of asphalt
paving. In addition, RLW will replace two bridges, as well as a number
of retaining walls, in addition to making improvements to drainage,
signage and landscaping.

Joe Cutillo, Sterling’s CEO commented, “This is another great win for
our Utah team. We have completed several important projects for UDOT in
recent years and are pleased to have once again been selected to help
enhance the state’s roadways. We’re particularly gratified to be
involved in making these significant improvements to the I-15 Exit 16
interchange since, once completed, our work will reduce congestion and
enhance safety for the large number of travelers that visit the area’s
many recreational areas, including Zion National Park.”
