The Ohio Dept. of Transportation is making ready to implement emergency repairs on the Daniel Carter Beard Bridge, which was not too long ago broken by an early morning fireplace under its southbound method.
The 1,300-ft-long twin tied-arch bridge, which carries a complete of eight lanes of Interstate 471 over the Ohio River between Cincinnati and Newport, Ky., was initially accomplished in 1976 and most not too long ago inspected Aug. 31, in response to the Kentucky Transportation Cupboard (KYTC). Its common every day visitors rely was about 51,000 in 2023.
Firefighters responding to a report of a hearth at about 3:20 a.m. on Nov. 1 discovered a playground burning below the bridge at Sawyer Level Park, which runs alongside the riverfront in Cincinnati. The trigger has not but been decided.
A minimum of three metal beams will have to be changed, says Matt Bruning, press secretary with the Ohio Dept. of Transportation (ODOT). So will an space of the bridge deck and an overhead signal truss. The southbound lanes are quickly closed, as is the left northbound lane.
The group used drones and a dog-style robotic outfitted with a Mild Detection and Ranging (LiDAR) scanner to evaluate injury, although a full evaluation will observe as soon as shoring towers are put in, Bruning says.
“As soon as they get that achieved, we’ll be capable to stand up there and get a better look, safely be capable to do a full inspection that can inform our choices on what precisely must be repaired, what portions of issues we’ll have to should make these repairs,” he says.
ODOT employed Hinckley, Ohio-based The Nice Lakes Development Co. to carry out the emergency repairs. And whereas Bruning says a value estimate just isn’t but obtainable, Gov. Mike DeWine declared a state of emergency in Hamilton County, enabling ODOT to make use of Federal Emergency Reduction Program funding for the work.
Thus far, crews have largely been centered on making ready footers and inserting a 3-ft-thick concrete pad for the shoring towers, which the contractor present in New Jersey, to stabilize the broken part. However their first job was to put in perimeter fencing, as Bruning says pedestrians utilizing the park had been transferring barricades and strolling by closed areas.

The preventative upkeep mission is being achieved now to make sure the Daniel Carter Beard Bridge, often known as the Massive Mac Bridge by locals as a result of its side-by-side “golden” arches, is in good situation forward of the upcoming Brent Spence Bridge Hall mission, which is able to contain constructing a brand new bridge carrying Interstate 71 and 75 throughout the Ohio River beside one other current bridge a few mile downstream.
Lexington, Ky.-based Intech Contracting LLC is changing growth stringer bearings, cleansing and repairing concrete obstacles and arch hangers, changing elastomer seals and hatches on the high of the arch and repairing some piers below a $4.2-million contract with KYTC.
With the southbound lanes closed for the emergency repairs on the southbound method, KYTC mentioned Intech would expedite work on the southbound facet without having to fret about visitors controls. Officers now say the mission will full forward of schedule inside the subsequent few weeks.
ODOT doesn’t at present have an estimate for when the emergency repairs will likely be full, although they need to transfer rapidly—visitors “has been horrendous,” Bruning says. The timeline will possible be decided by how lengthy it takes for supplies such because the substitute beams to reach.
“We’ll get this open as rapidly as we will, and get all people again on their method,” Bruning says.
