Although delayed, the Hyland-Croy and Post roads traffic signal should be operating by the week of Nov. 12.

Dublin officials had initially expected the signal to be in place by the end of September, but the project was held up because the signal mast arm delivery was later than expected.

Delivery was slower than expected because the supplier delayed production of the mast arm when orders exceeded their production capacity after another supplier went out of business earlier this year, said Paul Hammersmith, Dublin's director of engineering.

The mast arm has been erected, but the signal will remain covered as city engineers evaluate the light cycles during all time periods, said Lindsay Weisenauer, a Dublin public affairs officer. The signal is expected to be fully operational by the end of the week of Nov. 12, but the schedule is subject to change.

Union County and Dublin each provided $100,000 for the $200,000 project, said Megan O'Callaghan, Dublin's public works director.

Union County also shared in the design cost for the southbound right-turn lane added this summer, Hammersmith said. Dublin and Union County each paid $6,378.

Dublin and Union County are also working to secure funding for a larger improvement that includes an interchange at U.S. Route 33, state Route 161 and Post Road and a roundabout at the intersection of Hyland-Croy and Post, O'Callaghan said. The timeline is dependent on funding.

Planning and environmental analysis, design, rights-of-way purchase and utility relocations and construction for that project total $43.35 million, according to information from the city of Dublin.

Dublin contributed $17.6 million and Union County contributed $1 million. The Ohio Department of Transportation's Transportation Review Advisory Council awarded the county $7 million for construction, leaving a funding gap of $18 million.
