Polaris Parkway Arterial Street Rehabilitation
The City of Columbus, Department of Public Service selected Carpenter Marty Transportation to widen 0.57 miles of Polaris Parkway by adding a third eastbound lane from IR 71 to Olde Worthington Road and a third westbound lane from Olde Worthington Road to Orion Place. Orion Place was rebuilt to include a three-legged, two-lane roundabout at the intersection with Olde Worthington Road. Significant intersection upgrades, including modifications to five existing traffic signals, were part of this project.
The project also included the installation of a shared use path along the east side of Old Worthington Road/Orion Place and the south side of Polaris Parkway, retaining wall construction, landscaping, pedestrian upgrades, and street lighting. Substantial utility relocations and replacements were required with the roadway improvements, including waterline replacements, fire hydrant relocations and replacements, underground utilities, and complete storm sewer system reconstruction. Coordination between many project stakeholders was required, including City of Columbus, Delaware County, City of Westerville, ODOT, and MORPC. The project was designed over a period of 39 months, which included eight interim submittals. At the City’s request, the design was modified several times during plan development.
All City scheduled deadlines were met or accelerated by the design team. We accomplished this by establishing internal deadlines well in advance of the City’s schedule to ensure adequate time to review and check each submission. This reduced the number of comments received and limited the amount of design changes needed throughout plan development.
