Final Design Concept ReportI-10 Corridor Study, Tangerine Road to Ina Road Continuous two-lane, one-way frontage roadsReconstructing the Avra Valley Road TI to:o Shift the alignment approximately 80 feet east of the existing alignmento Pass over I-10o Widen Avra Valley Road to include a raised curbed median, four travel lanes (two travellanes in each direction) and left- and right-turn lanes as warrantedo Accommodate the future extension of Avra Valley Road to the north over the UPRR by theTown of Marana or othersReconstructing the Cortaro Road TI to:o Shift the alignment approximately 100 feet east of the existing alignmento Pass over I-10 and the UPRRo Widen Cortaro Road to include a raised curbed median, six travel lanes (three travel lanesin each direction) and left- and right-turn lanes as warrantedEX.0 EXECUTIVE SUMMARYThis Final Design Concept Report (DCR) describes the development, evaluation and recommendation ofimprovements to increase the capacity of Interstate 10 (I-10) between Tangerine Road (approximatemilepost (MP) 240.5) and Ina Road (approximate MP 248.7), for a total length of approximately eight miles.The project limits, as designated by the Arizona Department of Transportation (ADOT), extend from MP240.0 to MP 247.5. The proposed improvements shown in the DCR plans begin at existing I-10 Station4553 98 (MP 239.9) and end at existing I-10 Station 4993 00 (MP 248.2). This project is located inADOT’s Tucson District within Pima County in south-central Arizona. Project location and vicinity maps areprovided with Figures EX.1 and EX.2, respectively.The goal of this project is to develop and objectively evaluate transportation alternatives in order to moveahead a long-term master plan for this segment of I-10 in accordance with the approved regional and localtransportation plans, and other recently completed or on-going studies along I-10. This project will seek tooptimize the traffic operations within the corridor for the projected design year 2040 traffic demand, and tominimize or mitigate impacts the improvements may have on the surrounding community. Otherdocuments prepared to support this DCR include the following:The Recommended Alternative would:Operate at LOS ‘D’ or better during peak hours on all segments of the I-10 mainline and at the AvraValley Road and Cortaro Road TIs based on the traffic analysis performed with the projected 2040traffic volumesSupport the designation of I-10 as part of the CANAMEX trade corridor by maintaining acceptablelevels of service through the corridorReconstruct the frontage roads to be continuous and one-way; thereby providing a parallel route toI-10Upgrade the existing facilities to current design standards and practices. The drainage facilitiesconstructed with the Twin Peaks Road TI improvements would remain in placeEliminate vehicle-train conflicts on Cortaro Road. If the Town of Marana extends Avra Valley Roadto the north, the proposed improvements at Avra Valley Road would allow the northward extensionof this roadway with an overpass of the UPRR.Be compatible with ADOT, Town of Marana and Pima County long-range plansAlternative Selection ReportFinal Traffic ReportPreliminary Drainage ReportPreliminary Geotechnical ReportPreliminary Structure Selection ReportsEX.1 NEED FOR THE PROJECTI-10 is an existing freeway traversing the northern and eastern areas of Pima County. It is a majorcommercial corridor for intrastate, interstate, and international commerce. I-10 is one of the majorinterstate highways crossing Arizona and is part of an intercontinental corridor connecting the east andwest coasts of the United States (US). I-10 provides mobility for the communities along its route, and is aprimary carrier of commerce and interstate travel across the US.The improvements to the I-10 corridor are needed to address:Increased travel demand and traffic congestionCompromised efficiency of the Canada-America-Mexico (CANAMEX) Trade Corridor, aCongressionally-designated “High Priority Corridor”Lack of a continuous parallel route with direct connection to I-10 during major accidents or incidentsExisting facility not meeting current design standardsVehicle-train conflictsTo meet the project objectives and address the elements of need, the proposed improvements in theRecommended Alternative include:Expanding I-10 to add two travel lanes in both directions between Tangerine Road and Ina Road(ten-lane freeway) with a closed median (concrete median barrier)Lowering the I-10 profile at Avra Valley Road and Cortaro RoadParallel entrance and exit ramps in both directions on I-10 at all traffic interchangesEX-1February 2014

Portions of the eastbound entrance ramp and westbound exit rampfor the new Tangerine Road TI and the entrance and exit ramps at the Twin Peaks Road TI would bereconstructed.EX.2 DESIGN CONCEPT ALTERNATIVESThe design concept alternative development and evaluation process was divided into three categories asfollows:The continuous one-way frontage roads would generally be parallel to the I-10 mainline and would connectto the ramps near the traffic interchanges. The frontage roads would contain two 12-foot
