Orange cones and lane closures will pop up around Delaware County following the Ohio Department of Transportation's April 10 announcement of 2012 road construction projects.

For thousands of area motorists, a conspicuous example will be repair and resurfacing work along sections of U.S. Route 23 between Cheshire and Lazelle roads. The project will take place from June to October. Traffic will be restricted to one lane in each direction where work is taking place. The project cost is set at $4.19 million.

Another affected high-volume traffic area is the U.S. Route 36 and Interstate 71 interchange. Ramps will be widened to accommodate additional turn lanes on I-71, and the bridge over the interstate will be restriped. Lanes could be closed on I-71 during off hours during the construction period of May to November. The cost is set at $3.96 million.

ODOT spokesperson Nancy Burton said work, to be performed to improve safety, is not directly related to a much larger project at the interchange that's still at least two years away.

That project, estimated to cost at least $114 million, would renovate the interchange feeder roads. Its plan is so wide-ranging that county officials have said it could spur more development around the interchange.

Burton has said the more immediate safety improvements are needed, in part, because of the number of accidents at the site. According to ODOT, the interchange had 196 traffic crashes between 2008 and 2009, 50 percent of which were rear-end accidents.

Also on I-71, pavement will be repaired and resurfaced between Powell and Berkshire roads between May and September, costing $5.43 million. Single- and double-lane closures are expected.

Overall, ODOT's latest project list includes work totaling more than $41 million in Delaware County.

The other projects will:

• Repair the deck and replace sidewalks on the state route 37 (Central Avenue) bridge over the Olentangy River in the city of Delaware, from April to October. The work will cost more than $329,000 and is expected to include weekend closures.

• Resurface U.S. Route 36 and state Route 521 in Delaware, from May to October. The cost is $1.7 million and construction areas will have one-way traffic.

"Both projects are welcome, especially the much-anticipated U.S. 36 resurfacing," Delaware city spokesperson Lee Yoakum said. "This major east-west corridor serves many neighborhoods and travels through the heart of our city. It is essential to maintain this valuable section of infrastructure."

• Widen state Route 257 from Glick Road to the Columbus Zoo and Aquarium, from April to October at a cost of $3.26 million.

• Install a new deck overlay on the U.S. Route 42 bridge over the Scioto River. The project will cost more than $346,000 and will be performed from April to October. A temporary signal will direct one-way traffic.

Statewide, the ODOT list includes 56 approved projects. In a press release, ODOT director Jerry Wray noted the state would need more than $1.6 billion, money that's not available, to finish other proposed projects.
