3. CURRENT CONDITIONS AND FUTURE TRENDS

• Existing Conditions• Arterial Roadway• Access to Residential Neighborhoods

• Historical Perspectives

• Tilles Park Issues• Winter Wonderland

• Existing Operations• Peak Hour Congestion and Queuing

• Future Traffic Trends

4. ISSUES AND GOALS

• Primary Deficiencies and Likely Causes• Local Desires vs. Regional Network Realities• Traffic Flow Total Volumes• Safety• Convenience• Local Access

4. ISSUES AND GOALS (cont.)

• Goals for Improvement of McKnight Road Corridor1. Define appropriate functional class and let that guide decisions2. Volume reduction*3. Speed control4. Improve safety5. Truck control*6. Ease of access for residents7. Convenience of access for residents8. Accommodate bikes and pedestrians safely9. Maintain emergency access10.Comply with existing Winter Wonderland court order11.Secure Neighborhoods*

5. ALTERNATIVES AND ANALYSIS

• Identified Potential Alternatives

• Extremes – Road Closure or Widen to Five-Lanes

• Remove STOP sign for EB right-turn at off-ramp, not MUTCD compliant

• Remove STOP sign for NB McKnight at York (with alternative only)

• Signal Alternatives to Collect North Area Traffic, Restrict Other Connections

• Lindworth/York North – close to ramps• Ellsworth/York South – offset

5. ALTERNATIVES AND ANALYSIS (cont.)

• Identified Potential Alternatives

• Remark NB Approach for Two Lanes – South Ramps to Lindworth/York North

• Widen to Extend Two SB Lanes from Litzsinger North of Park Entrance

• Sign and Mark Interchange “Local Truck Traffic Only” (MoDOT/RH)

• Upgrade Sonora Crossing to Full ADA Compatibility

• Two Key Improvements and Three Alternatives Identified

Two Key Improvements

All Scenarios: Restripe for Two Northbound Through Lanes Between York North/Lindworth and Eastbound 64 Ramp

All Scenarios: Widen Pavement to Extend Second Southbound Through Lane at Litzsinger

Three Design Alternatives Identified

TillesPark

Concept 1: Signalize York North/Lindworth

Concept 2: Signalize Ellsworth/York South

Concept 3: Signalize Ellsworth/York South – 2 Southbound Through Lanes from I-64 to Litzsinger

5. ALTERNATIVES AND ANALYSIS (cont.)

• Other Solutions Considered

• Analysis• Delays, Congestion and Queuing• Downstream Gaps – Platoons vs. Metered• Bikes - Existing Shoulders, GBP calls for “Climbing Lane” Config• Winter Wonderland Accommodations

• Improve Real Time Monitoring and Info Distribution – MODOT TMC, DMS boards, etc.

• Resident Access and Convenience• Maintain Sonora Crossing – Active Beacons
