ADOT is using an accelerated bridge construction technique that will involve building the new bridge in two halves on either side of the existing structure, then sliding the sections into place. New piers will be constructed under the existing bridge to support the new structure as part of a process that will keep the bridge open while construction crews can work with only minimal disruption to traffic on SR 79.
The new bridge will include one lane in each direction. Unlike the existing structure, the new one will include eight-foot shoulders and a protected pedestrian walkway on the bridge’s west side. The $22.1-million project is expected to take about 18 months.
