OBERVATIONS / FINDINGS

EB K-18 Ramp & K-113 • Southbound Left-Turn Volume • Vehicles Begin Positioning North of

Southwind

Rosencutter Intersection • Westbound Left-Turn Movement (211 vph) • Outside Westbound Thru Queue • Not Enough Green Time for Eastbound

Thru Traffic • NB/SB Approaches along with Heavy WB

Left Reduces Eastbound Green Time • Consider Improvements at Rosencutter

VE JOB PLAN

ALTERNATIVE EVALUATION

Best performance with the greatest acceptance at a reasonable cost.

ROSENCUTTER / RICHARDS DRIVE

• Significant congestion is occurring • Overall intersection Level of

Service E • Eastbound thru movement

operates with a Level of Service F • Eastbound vehicle backup 25

vehicles • Multiple alternatives considered • Future improvements to Wildcat Creek

Bridges will impact the intersection

SPECULATION OF ALTERNATIVES FOR ROSENCUTTER / RICHARDS DRIVE

• Roundabouts • Overpass

• Widen Bridges at Wildcat Creek

• Dual Lefts • 6 lanes on K-18

• ITS optimization • Reduce speed on K-18

• Interchange at Rosencutter • Full access intersection

• Flyover ramp over Rosencutter

• Split diamond • Frontage roads

• K-18 under Rosencutter • Right in/Right outs • ¾ access

Alternatives to Consider ROSENCUTTER / RICHARDS DRIVE

Alternatives to Consider ROSENCUTTER / RICHARDS DRIVE

PROPOSAL DEVELOPMENT DDI and ¾ Access • Rosencutter/Richards

• ¾ Access • K-113

• DDI • Traffic Control at Allison

• Constructing Cost: $3.1 Million

PROPOSAL DEVELOPMENT Dual Left Turns and ¾ Access • Rosencutter/Richards

• ¾ Access

• K-113 • Dual Lefts for eastbound and southbound traffic • Maximum 7 lane section between ramps • 6 Lanes north of north ramp • Signals at both ramps

• Traffic Control at Allison

• Construction cost: $3.5 Million

Public Involvement

Methods • In-Touch • Post Cards • Community Voice • Phone Calls • E-mails

Themes • Bicycles and

Pedestrians in the Design

• Residential Access to K-18

• Roundabouts • Seth Childs and K-18 • Other

Diverging Diamond Operation



Bicycle & Pedestrian Facilities

WHERE ARE WE NOW?

Diverging Diamond Interchange • No Rosencutter Modifications • Currently in Design Phase • Looking at potential cost savings Est. Construction Costs have increased • Clearance Issues for Southbound Lane • Lower the Road Profile
