8 December 7, Project Overview – Existing Conditions

9 Crash Data TH 13/TH 101 intersection was ranked #18 on the statewide-list of Top 200 Highest Crash Cost intersections (Mn/DOT crash data from ) TH 13/TH 101 intersection was ranked #18 on the statewide-list of Top 200 Highest Crash Cost intersections (Mn/DOT crash data from ) Crash cost/year = $1.2 million Crash cost/year = $1.2 million 106 crashes in Project area 106 crashes in Project area 75% of those crashes were rear-ends crashes 75% of those crashes were rear-ends crashes 33% of those crashes resulted in injury 33% of those crashes resulted in injury December 7,

10 10 Project Benefits Safety - It is anticipated that the project improvements will reduce number of crashes at the intersection by around 80%. Safety - It is anticipated that the project improvements will reduce number of crashes at the intersection by around 80%. Mobility - Currently, the TH 13 and TH 101 intersection has a capacity of 4,400 vehicles per hour. The project will more than double the capacity of the intersection.

Floodplain - Raise eastbound lanes of highway above the 100-year floodplain elevation. Floodplain - Raise eastbound lanes of highway above the 100-year floodplain elevation. Bus Shoulders - Widen outside shoulders in each direction to accommodate buses. Bus Shoulders - Widen outside shoulders in each direction to accommodate buses.

13 December 7, Project Overview – Proposed Conditions Bridge eastbound Highway 13/Highway 101 Bridge eastbound Highway 13/Highway 101 (bridge is longer than initially proposed) Raise eastbound lanes above 100-year floodplain elevation Raise eastbound lanes above 100-year floodplain elevation Ramp construction Ramp construction Signalize lefts on and off westbound Signalize lefts on and off westbound Highway 13/Highway 101 Access closures/modifications Access closures/modifications Leave Highway 13/126 th St signal, but add pedestrian crossings Leave Highway 13/126 th St signal, but add pedestrian crossings

14 December 7, December 7, Access Closures/Modifications Highway 13 and Louisiana Avenue Highway 13 and Louisiana Avenue –From a full access, uncontrolled intersection –To full closure Highway 13 and Rhode Island Avenue Highway 13 and Rhode Island Avenue –From a right-in/right-out –To full closure Highway 101 and Zinran Avenue Highway 101 and Zinran Avenue –From a ¾ intersection –To right-in only

15 December 7, December 7,

16 16 December 7, Frequently Asked Questions Why didn’t Mn/DOT consider a design that eliminated the need for any signalized intersection, with access to TH 13 via ramps only? Would require grade separation of two bridges (a bridge over the eastbound bridge or two ramp bridges) Would require grade separation of two bridges (a bridge over the eastbound bridge or two ramp bridges) Grades would necessitate a change of access at Highway 13 and 126 th St Grades would necessitate a change of access at Highway 13 and 126 th St Many ramps are signalized at interchanges Many ramps are signalized at interchanges

17 December 7, December 7, Frequently Asked Questions The design still requires a weave to enter TH 169 northbound, vehicles will need to cross two lanes of full speed traffic, can the weave be eliminated? Would require a westbound bridge Would require a westbound bridge Balancing benefits and cost Balancing benefits and cost Weaving distances meet standards Weaving distances meet standards Looking to improve northbound TH 169 entrance ramp capacity during AM peak period Looking to improve northbound TH 169 entrance ramp capacity during AM peak period

18 December 7, December 7, Frequently Asked Questions Will this project really help traffic flow in the morning if no improvements are made to TH 169 northbound? Improvements made in stages Improvements made in stages I-494/TH 169 project I-494/TH 169 project Northbound TH 169 weave to Old Shakopee Rd exit ramp Northbound TH 169 weave to Old Shakopee Rd exit ramp Non-peak benefits Non-peak benefits

19 December 7, December 7, Frequently Asked Questions Can the access at Zinran Avenue be moved to the west to allow a right-out onto TH 13? If so, how far would it have to be moved? Corridor vision and access management Corridor vision and access management Intersection influence area Intersection influence area For weaving at Zinran Ave, 1500 feet minimum and 2000 feet desirable For weaving at Zinran Ave, 1500 feet minimum and 2000 feet desirable Only 200 feet from Zinran Ave to exit ramp Only 200 feet from Zinran Ave to exit ramp Eastbound grade rising for bridge Eastbound grade rising for bridge

20 December 7, December 7, Frequently Asked Questions If a right-out access onto TH 13 at Zinran Avenue cannot remain, can a right-out on the TH 13 southbound turn lane be designed? Intersection influence area Intersection influence area Speed differentials of high-speed deceleration Speed differentials of high-speed deceleration and low-speed acceleration Would need to weave on southbound TH 13 Would need to weave on southbound TH 13 to make U-turn at 126 th St signal

21 December 7, December 7, Frequently Asked Questions Can a right-in and/or right-out at Louisiana Ave be allowed until a traffic signal is installed at Dakota Avenue? Corridor vision and access management Corridor vision and access management Intersection influence area Intersection influence area Traffic on entrance ramp is accelerating, watching mainline traffic and preparing to merge Traffic on entrance ramp is accelerating, watching mainline traffic and preparing to merge Entrance ramp merge area to main line is at Louisiana Ave (no room for the 1500 – 2000 feet weave and a 500-foot turn lane for the right-in or the 1000 feet minimum – 1500 feet desirable for the right-out) Entrance ramp merge area to main line is at Louisiana Ave (no room for the 1500 – 2000 feet weave and a 500-foot turn lane for the right-in or the 1000 feet minimum – 1500 feet desirable for the right-out)

22 December 7, December 7, Frequently Asked Questions The local streets will take more traffic as a result of the access closures, does Mn/DOT have funding to offset any expected costs related to the local roadways? The City may use State Aid funding on designated Municipal State Aid Streets The City may use State Aid funding on designated Municipal State Aid Streets –Zinran Ave –126 th St

23 December 7, December 7, Frequently Asked Questions Will business signage be allowed that can direct traffic to the local businesses after construction is completed? During construction? Engineering Standards Engineering Standards Mn/DOT Policy Mn/DOT Policy Mitigation for construction impacts on businesses Mitigation for construction impacts on businesses

24 December 7, Project Construction and the Design-Build Process Michael Beer Mn/DOT Metro District — Eden Prairie Construction Resident Engineer

25 December 7, Design-Build Process Design-build is a contracting process that brings designers and contractors together early in the detail design portion of a project. The owner clearly defines the standards and general specifications they expect for a project, and the design-build team works together to satisfy those requirements.
