The construction of a new road off the state Route 161 and Industrial Parkway roundabout will start this fall.

Council last week accepted a $812,300 bid from the George J. Ingel & Co. Inc. to construct the first phase of Academic Drive on the city's west side.

The new road will extend south from the state Route 161 and Industrial Parkway roundabout and provide access to the Ohio University Heritage College of Osteopathic Medicine, which started classes in July.

The first phase of the project will consist of "650 feet of four-lane boulevard roadway including: curb and gutter, bike lanes, asphalt shared-use path, concrete sidewalk, brick pavers, water main, storm sewer and street lights," the staff memo to council stated.

Construction is expected to start this month and conclude by May 15, 2015.

State Route 161 is expected to remain open to traffic during the construction.

270/U.S. Route 33

In other city construction news, work on the Interstate 270-U.S. Route 33 interchange is expected to begin next year.

Council Aug. 25 approved a cooperation agreement with the Ohio Department of Transportation for the project.

According to City Engineer Paul Hammersmith, ODOT must get a cooperative agreement from any municipality participating in the project with them.

The interchange improvements will be conducted in two phases and in the first phase:

* Loop ramps in the northwest and southeast quadrants will be eliminated and replaced with new ramps that will pass over I-270 south of U.S. Route 33 and pass under U.S. Route 33 east of I-270.

* The southbound I-270 to westbound U.S. Route 33 movement will be split into two ramps for drivers exiting onto Avery-Muirfield Drive and one for drivers continuing west.

* U.S. Route 33 will be widened to four lanes in each direction between Avery-Muirfield Drive and I-270.

* A traffic signal will be added for drivers from northbound I-270 to eastbound U.S. Route 33.

Preparation for the project will get rolling in December with tree removal.

A construction contract for the project will go out to bid in January, Hammersmith said.

Construction could "begin toward the end of February/beginning of March 2015," the staff memo to council stated.

"Phase one will significantly improve the safety and operations of the interchange, removing the critical weave areas."

The second phase, which will eliminate the loop ramp in the northeast quadrant for a new ramp that will pass over U.S. Route 33 and I-270, is expected in 10 to 15 years.

The first phase of construction is expected to cost $73 million; $40 million will come from ODOT, the Mid-Ohio Regional Planning Commission will give $25 million and Dublin will contribute $8 million.

Dublin will also shell out $1.9 million for aesthetic improvements to the interchange such as concrete stamping on bridges and ramp walls.
