Interstate 70 - State Route 310 Interchange

                                 70-310 logo_small.jpg
This project is designed to address the poor condition of the existing SR 310 bridge over the interstate, as well as to upgrade the interchange and adjacent intersections for future traffic needs, as forecasted in studies by the Mid-Ohio Regional Planning Commission. 

Construction Update - Winter 2017​
  • Beginning early spring, both lanes of traffic will shift to the west, with north and south bound traffic traveling on the new bridge with one lane in each direction. During this time, the old northbound bridge will be demolished and the remainder of the new bridge will be constructed. This traffic setup should mirror the current configuration, and is expected to remain in place through the end of the summer. 

  • Ramp work is expected to begin early summer. The I-70 eastbound on-ramp from SR-310 will close for 18 days while that ramp is reconstructed. During this closure, eastbound traffic will be directed to take US-40 to SR-158 to access I-70 east. After the ramp reopens, work will begin on the I-70 westbound off-ramp onto SR-310. This will also require an 18 day closure while the work is performed. During this closure, westbound traffic onto SR-310 will be directed to exit at SR-158, and take US-40 west to SR-310. 

  • Late summer, SR-310 will close to through traffic for 18 days for culvert replacement and new pavement work. During this time, the interchange (ramps) will remain open to business traffic from I-70 only. Traffic north of the interchange will be directed to take US-40 east to SR-158 to enter I-70. Traffic south of the interchange will be directed to take SR-204 east to SR-158 to enter I-70. When that work is complete, the interchange will close to all traffic for 10 days while the remainder of new pavement work is completed. Traffic will be directed to follow the same routes as above, with access to the businesses surrounding the interchange from SR-310. To access businesses from I-70, traffic will follow the posted detour and enter from SR-310

  • Access will be maintained to all businesses during all phases of construction.

  • The Licking County Transportation Improvement District’s project to widen SR-310 from the northern limits of this project to US-40 is expected to begin this spring. Information about this project can be found at www.lctid.org. Efforts will be made to coordinate closures and detours between the two projects to minimize the impact on the traveling public.​

ODOT Preferred Design Alternative
Out of four alternatives, ODOT's preferred design will:
  • Replace and widen the bridge deck to accommodate six lanes (two thru-lanes each for northbound and southbound traffic and one northbound/southbound left turn lane each) as well as a walking/bicycling shared use path
  • Widen the eastbound off-ramp for additional lanes (two left turn and one right turn)
  • Widen SR 310 from Columbus Parkway to north of Dairy Queen Drive
  • Construct a shared-use path from Columbus Expressway to Etna Crest Boulevard (accommodates future pathway extensions)
  • Signalize the intersection of SR 310/Etna Crest Boulevard
Maintenance of Traffic
Construction is estimated to span from Spring 2016 to Fall 2017.​ Proposed impacts to traffic during construction will take place in three phases:
  • Phase 1: current southbound lane will close, with one lane each for north- and southbound traffic on current northbound side
  • Phase 2: Two lanes restored for each direction during winter season
  • Phase 3: current northbound lane will close, with one lane each for north- and southbound traffic on current southbound side
In addition, 14- to 21-day closures will take place at each interchange ramp, plus 7-10 day closures at the culvert locations on both the northern and southern ends of the bridge.

Estimated Project Schedule
  • Spring 2014: Public presentations to local community, with invitation for feedback
  • Fall 2015: Project construction plans complete
  • Spring 2016: Construction begins
  • Fall 2017: Construction ends
Estimated Costs and Funding Sources
Construction is estimated at $12,700,000 and right-of-way acquistion at $600,000. Funding will come from:
  • Ohio Department of Transportation: $4,500,000
  • Mid-Ohio Regional Planning Commission: $7,050,000
  • Etna Township (and other local sources): $1,760,000
