4 Agenda History Project Description U-Turn Configuration Construction of the Project Question & Answer Session

5 2000: Maricopa County Department of Transportation (MCDOT) Northwest Valley Transportation Study History October 2002: North Central Peoria / Northwest Glendale Circulation Study 2004 and 2005: Six Public meetings in Peoria and Glendale July 2006: Design Concept Report Completed ( peoria) Split the project and add Union Hills TI Widening May 2009: ARRA funding allocated for project November 2009: Construction began

6 High Volume at 101 Interchanges: 75 th Ave and Union Hills Extend Beardsley to the 101. Build Interchange where NEVER planned! Build Interchange In a Curve!?! Challenge All in another jurisdiction (Glendale) with Peoria Designing g a Freeway Interchange that ADOT has never built!!!

7 Conventional Diamond TI Depressed Mainline Elevated Fly Over Braided Ramps Pre-Signal U-Turn Alternatives Evaluated

8 Selected Alternative 101 Frontage Road: At Grade Union Hills & 75 th : Interchange Ramps Modifications o U-Turn Bridge Union Hills: Interchange Widening

9 Additional Project Enhancements Roundabout at 81 st Avenue and Beardsley Speed Cushions on 81 st Ave North/South of Beardsley Free right turn lane at 83 rd Avenue Di t A t NB Direct Access to NB SR 101L from Beardsley from the U- Turn Structure

10 Typical Texas U-Turn Configuration Turning radius: commercial truck Seperated from crossroad with curbed island Departure merges with ramp/frontage road

11 Beardsley U-Turn Configuration Crossroad / ramp separation barrier Approach separated from frontage 950 prior to intersection Departure separate entrance to freeway

12 Beardsley U-Turn Configuration Turning radius WB-67 Di bl d hi l Disabled vehicle bypass

13 Union Hills Interchange Widening

14 Differences Between Texas U-Turn and Beardsley U-Turn Physical separation between the U-Turn and adjoining roadways Reduced interaction between U-Turn and adjoining roadway traffic Increased capacity of the facility Use of emergency shoulder Possible Over Design?

15 Results Amazingly it fit! Frontage Road? Limited Access Collector Distributor? Only one street Arizona U-Turn?
