Progress Photos: Carolina Crossroads Construction (Columbia, SC)

Columbia, SC - Archer-United, the joint venture of Archer Western Construction and United Infrastructure Group, along with the lead design firm, Infrastructure Consulting & Engineering are constructing the first two concurrent phases of the South Carolina Department of Transportation's Carolina Crossroads project. The five-phase project will improve “Malfunction Junction,” the interchange at I-20, I-26 and I-126 on the northwest side of Columbia.

Phase 1 of the project consists of the re-design and construction of a new interchange for Colonial Life Boulevard at I-126, as well as improvements on I-26 and I-126. Archer-United will replace the existing adverse weave on I-26 westbound between I-20 and I-126 with a semi-directional interchange that is safer and operationally more efficient. Phase 1 stretches approximately 2.5 miles and also includes the reconfiguration of the secondary\frontage roads, three new bridges and two bridge deck rehabilitations.

Phase 2 will update the Broad River Road interchange at I-20 in order to create better traffic flow to the interstate as well as lengthen I-20 westbound's access to I-26 westbound in order to minimize congestion from vehicles changing interstates. Three new bridge structures will also be constructed within Phase Two.
