When will work begin and what can we expect during construction?

Construction is expected to start early this spring and be completed by the end of 2023. SR 89A will remain open to traffic with the exception of limited daytime and overnight closures. Once construction starts, the highway will be narrowed to one lane only through the work zone(s) with alternating northand southbound travel. Traffic-control will be maintained using a combination of temporary traffic signals and/or a flagging operation. ADOT is committed to completing the improvements as quickly as possible, while balancing the transportation and access needs of local communities.
