I-70/I-71 Downtown Ramp Up
The Downtown Ramp Up is a series of projects to reconstruct Interstates 70/71 in downtown Columbus and alleviate the biggest safety and congestion problems along the corridor. ODOT has already invested more than $400 million into the interchange improvements, and construction of another three projects worth $480 million will begin in the next four years.
The projects were undertaken due to high crash rates and heavy congestion into and out of downtown Columbus. When complete, the projects will result in new urban avenues with complete streets, enhanced freeway crossings with safe pedestrian and bicyclist accommodations, and the removal of unsafe ramps.
Upon completion of all phases, this $1.4 billion mega project will:
- Improve safety at three of the state’s top ten crash locations
- Fix the biggest safety and congestion issues along the I-70/71 downtown corridor
- Build an additional lane in each direction on I-70/71
- Provide two continuous lanes for I-70 east and west and for I-71 north and south through downtown Columbus (not including ramp lanes)
- Eliminate nearly 70% of lane changes on I-70/71
- Eliminate free-flow ramps at downtown street intersections for safer pedestrian crossings
- Reconnect neighborhoods by replacing bridges with wider, pedestrian-friendly structures with parking and landscape design
Access to Nationwide Children's Hospital
Traffic must exit via Parson Avenue ramp
Interstate 70 eastbound drivers headed to Nationwide Children's Hospital now must use a new exit ramp. Instead of exiting at 18th St. as drivers have in the past, the new ramp lands motorists at the intersection of Parsons Avenue and Mooberry Street.
This means the decision point for I-70 east drivers comes much sooner than before. Traffic wishing to access Nationwide Children's Hospital or Parsons Avenue will exit the highway on the right just past 4th Street, before the through lanes shift to the left. Parsons Avenue traffic should stay to the far right to exit, and traffic that wants to continue on I-70 east should stay left.
Along with the interstate changes, traffic on Parsons Avenue will now come to a signalized intersection at Mooberry Street and should be prepared to stop.
Additionally, the eastbound exit ramp to 18th Street is now closed permanently. This closure allows crews to begin rebuilding I-70 east over Parsons Avenue.
