Project Background

Six Study Locations

1. SR 46/SR 82 (EB Ramps) 2. SR 46/SR 82 (WB Ramps) 3. SR 82/Howland-Wilson Road 4. SR 46/Warren-Sharon Road 5. SR 46 from Warren-Sharon to SR 82 6. SR 46/Howland Springs Road

Expands upon previous studies/projects

2005 TRU-422 Corridor Study
2006 SR 82/Howland-Wilson Road Improvements
2012 SR 46/SR 82 Turn Lane Improvements
2012 SR 46 Corridor Signal Re-timing

Network Interconnectivity

The study area is a connected network

Congestion at one location spills back

through the network

Improvements at one location can have

both positive and negative impacts at the

thers
Careful balance of improvements

necessary

SLIDE 8

Network Interconnectivity

Howland-Wilson Road serves

as a “pressure relief valve” for the SR 46/SR 82 interchange

Issues heightened by existing

inefficiencies at SR 46/SR 82

Present Day Conditions

Congestion occurs throughout the day Multiple peak periods

AM (7:00a-9:00a)
Midday (11:00a-1:00p)
School Release (2:00p-3:00p)
PM (4:00p-6:00p)

Network Congestion

SLIDE 13

Present Day Conditions

Crash trend increasing
60-75 crashes per year (study area average)
Majority of crashes are rear end crashes
Injury Crashes
30% of all study area crashes
>40% of SR 82/Howland-Wilson Road Crashes
Increasing congestion

Proposed Countermeasures

SLIDE 17

TRU-422 Corridor Study

The TRU-422 (2005) Corridor Study Evaluation

Previous alternatives were rejected because of:

Potential right of way impacts
High construction costs
Construction feasibility
Low safety benefit

Previously Considered Alternatives

SLIDE 18

Proposed Countermeasures

SR 46/SR 82 Interchange

Replace the existing interchange with a Diverging Diamond

Interchange (DDI)

Provide pedestrian access through the interchange

Why Choose a DDI? 30% Less Driver Delay Overall 25% Less Driver Delay at Interchange 50% Fewer Vehicle Stops

SLIDE 24

Proposed Countermeasures

SR 82/Howland-Wilson Road

Restrict access to Right-In Only from SR 82 (Eastbound/Westbound)
Remove traffic signal
Cul-de-sac northbound and southbound Howland-Wilson Road
Fire/EMS access maintained
