Hayden Run Road east of Britton Parkway is scheduled to close June 19 for a project related to new construction at the adjacent complex for Vadata, an Amazon subsidiary that builds data centers.

The closure, which involves replacement of a culvert west of the Interstate 270 overpass to facilitate a widening project, is scheduled for eight weeks, said Clark Rausch, Hilliard's deputy city engineer.

He said detours would be posted.

The project entails widening only the shoulders of Hayden Run Road, said Letty Schamp, Hilliard's deputy city engineer. The road's layout of one traffic lane in each direction would not change, she said.

The engineer's estimate for the Hayden Run Road improvement was $838,500, and the city awarded the project earlier this year to Trucco Construction Co. for $816,500, Rausch said.

The contract includes a contingency that allows for the expenditure of $897,500, he said.

Meanwhile, construction has been underway for several weeks on the second of three data centers belonging to Vadata.

The first 183,000-square-foot data center was completed last year.

According to a building permit the city issued in October 2016, the second data center appears to be slightly smaller in size at 152,945 square feet.

"We are expecting plans for the third building soon, which will be reviewed (for consistency) with the provisions ... of the development text," said John Talentino, Hilliard's city planner.

Letty Schamp, Hilliard's deputy city engineer, said city officials have been coordinating with local representatives on the latest project but that two individuals from Vadata were present at a May 4 conference on the current construction project.

Ann McGee, whose name and phone number is listed on the building-permit application as the applicant/contact, would not speak about the construction project. She cited a nondisclosure agreement concerning any activity at the site, past, future or present.

Similar agreements have resulted in limited information from both Vadata sources and local governments since the data-center projects in Dublin, Hilliard and New Albany began in 2015.

The building-permit application also lists the builder/contractor as Holder Construction and the owner/tenant as Vadata. The application did not specify an address for Holder Construction, but a local company of the same name is based in New Albany.

Other construction details

American Electric Power also has been relocating utilities on the east side of Britton Parkway near the data-center site.

"AEP is upgrading the lines for a power substation that was built for the Amazon center," Rausch said.

The new lines will increase capacity and the project is expected to be completed this week, according to a spokesman for AEP.

In addition, Hilliard's project to widen the shoulders of Hayden Run Road between Britton Parkway and I-270 will include a multiuse recreation path on the north and south sides of the road in the city's boundaries, Rausch said.

However, the multiuse paths would not extend under the I-270 overpass bridge, according to current plans for the project.

Councilman Les Carrier is seeking to change that.

"We are always looking for opportunity for connectivity," Carrier said.

He said he is concerned about the risk of people navigating their own path under I-270 to reach paths at Hayden Lofts to the immediate east.

Hilliard's boundary line ends at the I-270 bridge. Columbus and Dublin are on the other side.

Rausch said a path under the I-270 bridge would have to involve the Ohio Department of Transportation.

Carrier said he has reached out to state Sen. Stephanie Kunze (R-Hilliard), a former Hilliard councilwoman, to seek her assistance in lobbying for the path's connection.

ODOT already is doing work in the area this summer to refurbish bridge decks and ramps, Carrier said.

"It makes perfect sense (to make that connection) now," he said.

Kunze said ODOT is working with the Franklin County Engineer's Office to gather more information about the proposal.

"ODOT needs this information to determine whether or not it is possible to add on to another project that was previously approved, and to analyze if there are any negative impacts," she said.

"I will continue to monitor progress from ODOT and look forward to working to find a way to safely connect our communities."
