2 Public Informational Meeting Meeting Agenda o Welcome and Introductions o Route 20 Project Overview o Route 20 Project Update o Next Steps o Public Comments and Questions & Answers

3 Route 20 Reconstruction Charlton- Oxford Limits of Project o Begin at Richardson Corner Rd, Charlton o Extend 3.2 miles east to Rte. 12, Oxford Approx. 26,000 vehicles/day Majority of intersecting roads are residential collector roads

4 Existing Conditions West of Route 56 Corridor lined primarily with commercial/industrial businesses East of Route 56 Residential Pocket Community, Thayer Pond Condos Two 11 foot lanes each direction with 1 outside shoulders Double yellow centerline painted over rumble strip Mobil Gas/Convenience Store Residential Neighborhood

5 Existing Conditions Signalized intersection at Rte. 56 o Crash rate = 1.35 accidents per million entering vehicles o Higher than District 3 (0.93) and statewide averages (0.82) for signalized intersections Road Safety Audit (RSA) completed for Rte. 56 intersection - January, 2015 RSA completed for Rte. 20 corridor April, 2016 Rte. 20 at Rte. 56 Looking West Rte. 20 at Rte. 56 Looking East

6 Interim Safety Improvement Measures Richardson Corner to Oxbow Road o Signage indicating Trucks Prohibited from Left Lane o Vegetation Clearing increase side distance o Install Reflective Stanchions o Additional Signage Rte. 20 at Bay Path Road Looking East Rte. 20 at Oxbow Road Looking East

7 Interim Safety Improvement Measures Curve Near Oak Drive/Oxbow Road o Widened and resurfaced the roadway 3-6 feet each side o Double faced thrie-beam median guardrail o Permanent speed feedback signs o Dynamic, lighted curve warning signs and chevrons Rte. 20 at Town Line Looking East Speed Feedback Sign at Rte. 20/Oxbow Intersection Rte. 20 Curve at Oak Drive Looking East

8 Limited Right of Way The purpose of the project is to improve the safety and traffic operations of the roadway and intersections. Challenges Limited roadway Right of Way Alignment Deficiencies Alignment deficiencies Resource areas Impaired water bodies Rare and endangered species Wood Turtle Impaired Water Bodies Resource Areas

9 Existing Cross Section Proposed Cross Section Full depth pavement reconstruction and roadway widening Median barrier Roadway alignment improvements Sidewalks at Rte. 56 Intersection and east of Rte. 56 intersection

10 Proposed Project Improvements Richardson Corner Road to Route 12 Bridge improvements o Little River reconstruction/widening o French River full replacement o Phased construction Full U-turn locations o Route 12 o Route 56 o Oxbow Road o Richardson Corner

19 Project Update New Survey Baseplan July, 2016 Rte. 20 Roadway Safety Audit April, 2016 Subsurface Exploration Program January, 2016 thru January, 2017 Design Build Procurement Alternative Intersection Concepts at Rte. 56 FHWA Every Day Counts Innovation Improve Safety Improve Operations

20 Route 56 Intersection Advantages Less ROW and Frontage Impacts along Rte. 20 and Rte. 56 Improved Safety less conflict points = less accidents Improved Operations intersection capacity and travel time

32 BUILD ALTERNATIVE AVERAGE DELAYS WEEKDAY AFTERNOON PEAK HOUR 0-20 sec >20-35 sec >35-55 sec >55-80 sec >80 sec

33 Route 56 Intersection Travel Times Estimated travel times for through movements on Route 20 and Route 56 are less than or same as conventional intersection design o Fewer signal phases provides more green time to each signal phase Travel times for some left-turn / u-turn movements increase, due to longer path to complete the movement
