SH-82 ALIGNMENT STUDY FROM THE INTERSECTION OF SH-82 AND SH-100 EXTENDING EAST AND NORTH TO JUST SOUTH OF SNAKE CREEK SEQUOYAH COUNTY Open House November 15, 2016

PRESENTATION OUTLINE  Background – Purpose and need for the project  Scope – Design constraints  Environmental – Environmental review process  Design Alternatives – Five alignment alternatives  Summary – Matrix, timeline and public comments SH-82 Scope Background Environmental Alternatives Summary

MEETING PURPOSE Present and solicit input for the proposed improvements of SH- 82 from the intersection of SH- 82 and SH-100 extending east and north to just south of the Snake Creek Bridge in Sequoyah County, and to obtain public input to aid in selecting a preferred alternative. Scope Background Environmental Alternatives Summary

PROJECT BACKGROUND  This segment of SH-82 was originally a county road and doesn’t meet current highway design criteria  Unsafe curves with poor sight distance  High accident rate Unsafe Curves Scope Background Environmental Alternatives Summary

EXISTING ALIGNMENT  Two, 11-foot driving lanes  Poor horizontal and vertical curves Poor vertical curve Poor horizontal (limited sight distance) curves No shoulders & Steep slopes Scope Background Environmental Alternatives Summary

EXISTING ALIGNMENT Rocks preventing  Poor sight distance to see clear sight around corners  Skewed intersections with limited sight distance Unsafe intersection Scope Background Environmental Alternatives Summary

ACCIDENT DATA (2006 TO 2016) Current traffic (2016): 1,460 vehicles/day Project 30 year traffic (2046): 2,580 vehicles/day  Over 4.5 times more accidents than the state average  Fatal collision rate is 540% higher than the state average  Three (3) fatalities Skewed intersection at SH-82 and E 970 Road Scope Background Environmental Alternatives Summary

ACCIDENT DATA Accident History in Relation to Unsafe Curves and intersections (2006 TO 2016)  94% of the accidents occurred at poor curves or dangerous intersections Type of Collision Fixed Objects 56.7% Overturning 28.4% Angle Turning 4.5% Head-On 3.0% Miscellaneous 7.4% Scope Background Environmental Alternatives Summary

PROJECT SCOPE  Improve safety beginning at the intersection of SH-82 and SH-100 extending north and east to Snake Creek Bridge.  Analyze five alternative alignments  Perform an environmental review  Incorporate the Cherokee Hills Scenic Byway Plan Background Scope Environmental Alternatives Summary

PROPOSED DESIGN  Improve horizontal and vertical curves to increase safety  Correct sight distance around curves  The existing highway is to Proposed Roadway remain open during • Two, 12-foot driving lanes construction • 8-foot shoulders • Open drainage ditches • 55 or 65 mph design speed Background Scope Environmental Alternatives Summary

ALIGNMENT ALTERNATIVES  Considered five alignment alternatives  Alt. 1 - Rehabilitation with curve corrections of the existing alignment to meet a 55 mph design speed.  Alt. 2 – Reconstruction with an offset alignment to the east at a 55 mph design speed.  Alt. 3 - Reconstruction with an offset alignment to the east at a 65 mph design speed.  Alt. 4 - Reconstruction with an offset alignment further east at a 65 mph design speed.  Alt. 5 - Reconstruction with an offset alignment to the west at a 65 mph design speed.  Considered topography, right-of-way and utility impacts plus environmental constraints. Background Solution Environmental Alternatives Summary

ALTERNATIVE 1 Rehabilitation with curve corrections of the existing alignment to meet a 55 mph design speed.  New alignment to correct curves while keeping traffic open  Majority of the alternative runs parallel to existing on the east side  Utilizes approximately 2,200 feet of existing highway  Does not correct vertical curve south of Snake Creek  Least environmental impact  Potential impacts to commercial property, community facility and residences  Estimated total alternative cost of $21.1 million Alternative 1 Background Solution Environmental Alternatives Summary

ALTERNATIVE 2 Reconstruction with an offset alignment to the east at a 55 mph design speed  No curves north of EW-97 Road meet 65 mph  The new alignment runs east of existing  Utilizes 1,000 feet of existing highway  Corrects vertical curve south of Snake Creek where accidents are frequent  Potential impact to three residential properties  Estimated total alternative cost of $20.3 million Alternative 2r Background Solution Environmental Alternatives Summary

ALTERNATIVE 3 Reconstruction with an offset alignment to the east at a 65 mph design speed  Located slightly east of Alternative 2  Potential impact to five residential properties  Estimated total alternative cost of $30.6 million Alternative 3 Background Solution Environmental Alternatives Summary

ALTERNATIVE 4 Reconstruction with an offset alignment further east at a 65 mph design speed  Located furthest east of all alternatives  Mountainous terrain and a plateau with steep slopes  Most potential for environmental impacts  Most potential to impact residential properties  Estimated total alternative cost of $37.5 million Alternative 4 Background Solution Environmental Alternatives Summary

ALTERNATIVE 5 Reconstruction with an offset alignment to the west at a 65 mph design speed  Straightens the intersection at SH-100, SH-82 and NS-4515 Road  Location of several accidents  Most direct and shortest route  Potential impact to businesses  Estimated total alternative cost of $28.7 million Alternative 5s Background Solution Environmental Alternatives Summary

CHEROKEE HILLS SCENIC BYWAY The Cherokee Hills Scenic Byway was created to “tell the story of NE Oklahoma that captures the culture, traditions and beauty of the land of the Cherokee people.”  Scenic byway begins in Gore and ends in West Siloam Springs  Located within the scenic byway  The Byway program includes  Possible scenic overlook Possible Scenic  Reducing accidents in rural Overlook areas  Economic development Scenic Turnout Opportunities Background Solution Environmental Alternatives Summary
