DBA submitted a bid to ADOT for the demolition and reconstruction of two bridges in Yuma County over the Mohawk Canal. Located off the ADOT highway system on Avenue 37E and Yuma County’s 6th Street is one bridge. The other bridge is located on Avenue 46E and Yuma County’s 1-1/2 Street. Both bridges require the removal and replacement of the bridge girders, removal and replacement of the bridge railing/barriers, construction of new bridge abutments, removal and replacement of the asphaltic concrete pavements on the deck and additional 50-foot approach slabs will be constructed.
DBA crews started on the project in late August and expect to be complete by the end of 2019. The bridge construction is directly over an irrigation canal that is used for the agricultural community in Wellton. As a result, extensive measures have been taken to protect the water from construction debris and chemical intrusion.
