Along the Segment 2A project – Sahuarita Road – drivers will notice the new embankment, concrete vertical curb, a rock lined drainage channel, and initial asphalt pavement that has been placed along side of the existing Sahuarita Road. These new roadway improvements represent a widened (4-lane) Sahuarita Road. The contractor has completed the installation of the new eastbound bridge across the Santa Cruz River. Over the next several weeks the contractor will focus their work on constructing the new sidewalk and drainage scuppers between the new bridge and La Villita Road, as well as the earthwork associated with the new westbound lanes. Below the new bridge, the remaining portions of the new soil cement bank protection are being installed to shield the new bridge approaches from the flows of the Santa Cruz River.
All Sahuarita Road traffic, between La Villita Road and the realigned Nogales Highway, has been shifted to the new eastbound lanes (and onto the new bridge at the Santa Cruz River). This traffic shift is allowing the construction of the future westbound lanes and the westbound bridge across the Santa Cruz River (see map). Speed limits will be reduced in the vicinity of traffic shift for the safety of the workers and traveling public.
The Segment 2B project – Nogales Highway Realignment – is also taking shape as concrete vertical curb and final asphalt pavement have been installed along the new Nogales Highway alignment and its new intersection with the widened Sahuarita Road. The new Nogales Highway alignment is approximately two-miles in length, roughly one-mile on each side of Sahuarita Road. Lane striping along the new Nogales Highway realignment will be installed during the months of June and July. Both northbound and southbound traffics may be shifted edge of the exiting Nogales Highway and speed limits may be reduced in the vicinity of traffic shifts for the safety of the workers and traveling public.
