Roberts Road Construction Underway
Diverging Diamond Interchange coming to I-270 and Roberts Road
COLUMBUS – (NEW) The contractor has started work, surveying and clearing brush, for the new interchange at I-270 and Roberts Road on the west side.
ODOT plans to build a diverging diamond interchange (see below). As its technical name suggests, the interchange would be shaped like a diamond and would reduce congestion and improve traffic flow by:
· Switching traffic to the opposite sides of the road as it passes over the freeway; and
· Constructing entrance ramps to I-270 that are free-flow turns
To save time and improve efficiency, ODOT engineers determined if the Roberts Road bridge was closed completely, instead of maintaining one lane in each direction, construction would be complete in half the time or six months.
The bridge can be closed for a maximum of 90 days bridge, but all ramps at the interchange will remain open. East and westbound Roberts Road would be detoured using the I-270/Cemetery Road Interchange, Westbelt, Trabue and Wilson Roads There is an incentive for the contractor, Shelly and Sands, to open the bridge early.
While it is not known exactly when the Roberts Road Bridge will close, the contractor estimates it will be near the end of July. The contractor will also close Wilson Road at Roberts for 15 days for intersection improvements. That work must be completed and Wilson Road opened before the Roberts Road Bridge closes.
ODOT is investing an estimated $9.7 million at I-270 and Roberts Road. The interchange averages just over a hundred crashes a year.
