North High Street Widening and Rehabilitation

JMT designed widening for a major arterial roadway while maintaining traffic during construction.

North High Street, a major arterial in Ohio’s capital city, was widened from five to seven lanes. JMT provided design engineering services for nearly one mile of roadway, as well as maintenance of traffic (MOT), pavement markings, signing, traffic signals, lighting, and utilities. It was necessary to maintain two lanes of traffic in each direction and keep all the intersections and driveways open during construction. Sidewalks were added on the west side, and a multi-use trail on the east side, both with ADA-compliant curb ramps, turn lanes, curb and gutter, and drainage improvements including storm sewers.

JMT upgraded the existing, closed drainage system to accommodate drainage from the increased pavement width. An extensive new drainage system throughout the length of the project features both open drainage ditches and a closed scheme with new inlets, catch basins, and manholes. Other improvements included traffic signal upgrades with vehicle detection and interconnect systems, intersection widening and turning radius upgrades, traffic control modifications (signals, signs, and pavement markings), roadway lighting, and MOT and right-of-way plans.
