Crews have begun construction on Phase 2 of the Tangerine Road Corridor after a design period conducted by civil engineering company Psomas. The second portion was split into Phases 2A and 2B to accommodate planned industrial development by Southern Arizona Logistics.The Tangerine Road Corridor project is a part of the town’s Capital Improvement Projects plan.“Roadway users can expect a very similar look and feel to the completed Phase 1 section,” said Tom Houle, capital improvement plan project manager.
“The main improvements include additional travel lanes, turn lanes, a curbed median, pedestrian and bicycle facilities, traffic signals and drainage improvements.”Phase 2A runs from I-10 East to the Tangerine Business Park for 2 1/2 miles, and will include a new traffic signal on the Adonis Road intersection.Phase 2B will complete the road widening to four lanes between Tangerine Business Park and Dove Mountain Boulevard. It will also include wildlife crossings and a 100-year flood access roadway.“Some of the culverts on Tangerine Road are designed to perform double duty, both to convey drainage and as a means of wildlife crossings,” Houle noted.The design team worked with the Arizona Game and Fish Department to analyze the types of wildlife that would cross the road. Arizona Game and Fish reported high animal usage from the video cameras it installed along the established Phase 1 crossings.
The Tangerine Road Corridor is also designed to prevent flooding from a 100-year storm, which is defined as a rainfall event with a 1% chance of occurring in any given year.“We create 100-year flood access by performing hydrologic studies to determine how much water will hit the roadway corridor in this event,” Houle said. “Then, (we designed) a system of channels to capture that water and direct it to drainage culverts to take it under the roadway and downstream.”Both features …
