3 TANGERINE ROAD CORRIDOR I-10 to La Cañada Drive

4 TANGERINE CORRIDOR PROJECT NEED Why improve Tangerine Road? Roadway closes during flooding Some segments nearing capacity limited passing opportunities No pedestrian facilities Need to plan for future growth Photo from AZ Daily Star July 5, 2012

5 TANGERINE CORRIDOR PROJECT ELEMENTS Goal: Improved multi-modal mobility and safety Widening to 4 lanes from I-10 to La Cañada (10 mi) Landscaped median Multi-use lanes, sidewalks Drainage improvements (eliminate dips) Intersection Improvements

9 SEGMENT 1 DESIGN Dove Mountain Blvd to La Cañada Drive

10 SEGMENT 1 PROPOSED IMPROVEMENTS Widening to 4 lanes from Dove Mountain Blvd to La Cañada Dr (5 mi) Landscaped median Multi-use path, bike lanes Drainage improvements Five wildlife crossings Signalized Intersections Dove Mountain Blvd Thornydale Road La Cholla Blvd Resurfacing of Thornydale Road in Marana Limits approximately 0.4 mi North and 1.0 mi South of Tangerine

11 SEGMENT 1 PROPOSED IMPROVEMENTS Dove Mountain Blvd to Camino de Mañana (1.5 mi) Desert Parkway design Uncurbed, limited access 50 mph speed limit Native Vegetation, water harvesting No impacts to structures

12 SEGMENT 1 PROPOSED IMPROVEMENTS Camino de Mañana to La Cañada Dr (3.5 mi) Arterial design - Curbed median (similar to section east of La Cañada) 45 mph speed limit No impacts to structures

13 SEGMENT 1 PROPOSED IMPROVEMENTS Key Changes since last Public Meeting (January 15) Added dedicated entrance to Tangerine Corridor Park (Marana)

14 SEGMENT 1 PROPOSED IMPROVEMENTS Key Changes since last Public Meeting (January 15) Changed Camino de Oeste from a signal to a HAWK (High-Intensity Activated Crosswalk).

15 SEGMENT 1 PROPOSED IMPROVEMENTS Key Changes since last Public Meeting (January 15) Shifted drainage channels farther from road/pathway Creates space for additional landscaping along pathway 60% Design Current Design

16 SEGMENT 1 PROJECT DESIGN STATUS 100% Plans complete in December Coordinating project design with utility companies Utility relocation designs currently being finalized Relocations to begin as soon as December Property Acquisition Status Arizona State Land right of entry expected by end of 2015 Continuing negotiations with private property owners Coordinating design and construction elements with Construction Manager at Risk (CMAR)

17 SEGMENT 1 PROJECT DESIGN STATUS Recap of CMAR Delivery Method: Quality Uses most qualified contractor, not lowest bidder Contractor brought in during design Design engineer, owner and contractor work together to improve constructability and reduce impacts Contractor can suggest cost and time savings construction methods Can allow early start of some construction activities CMAR for Tangerine Road: Tangerine Corridor Constructors (TCC) (a Granite, Borderland Joint Venture)

18 SEGMENT 1 CONSTRUCTION Dove Mountain Blvd to La Cañada Drive Tangerine Corridor Constructors

19 SEGMENT 1 CONSTRUCTION Meet Tangerine Corridor Constructors (TCC)

20 SEGMENT 1 CONSTRUCTION Our Projects you may be familiar with State Route 77 (Oracle Rd.) Tangerine Rd to Pinal County Line Twin Peaks Rd: Linda Vista Blvd to Tangerine Rd

21 SEGMENT 1 CONSTRUCTION Approach to Construction: Maintain two-way traffic along Tangerine Road Maintain access to all residents and businesses Maintain bicycle/pedestrian access Minimize speed reduction and temporary traffic control devises Methods to maintain traffic/access: Sequence construction to build ½ of new roadway, while traffic is maintained on the existing roadway Temporary Traffic Control (Pavement Markings, Vertical Panels, Barricades, Barriers) Temporary Lane Shifts Temporary Asphalt/Detours

22 SEGMENT 1 CONSTRUCTION TYPICAL DRAINAGE SEQUENCE

23 SEGMENT 1 CONSTRUCTION PHASE ONE Work Sequence Detour Paving EB Drainage (Outlet) Barrier Dividing Traffic and Work Area

24 SEGMENT 1 CONSTRUCTION PHASE TWO Work Sequence Fill/Pave Over EB Drainage Detour Paving Removed WB Drainage Installed

25 SEGMENT 1 CONSTRUCTION PHASE THREE Work Sequence Fill/Pave WB Lanes Remove Temp EB Drainage Paving Flip Traffic to Design WB Lanes

26 SEGMENT 1 CONSTRUCTION PHASE FOUR Work Sequence Fill/Pave EB Lanes Striping For Design Traffic Open Traffic to All Lanes

29 SEGMENT 1 CONSTRUCTION PHASE TWO SE Quadrant

30 SEGMENT 1 CONSTRUCTION PHASE THREE SE Quadrant

31 SEGMENT 1 CONSTRUCTION PHASE FOUR SE Quadrant

32 SEGMENT 1 CONSTRUCTION Anticipated Construction Phasing/Sequencing: Dependent on utility relocations and right-of-way acquisitions Construct outlet side of new drainage structures first Construct new intersections in quadrants early in project New Westbound Tangerine Rd (Dove Mountain to Thornydale) New Eastbound Tangerine Rd (Dove Mountain to Thornydale) New Westbound Tangerine Rd (Thornydale to La Cañada) New Eastbound Tangerine Rd (Thornydale to La Cañada)
