MARIETTA, OK - Workers are replacing part of Interstate 35 at the Marietta exit.
All traffic is now forced to use one side of the interstate, and underneath cones are in place along Highway 32 as crews build a new overpass for each side of traffic.
"The bridges at that location are very narrow for interstate traffic," ODOT engineer Jay Earp said. "They're functionally obsolete."
"It's a pretty old bridge," driver Clay Pickens said. "There's been a lot of accidents on it, hunks of concrete missing out of it."
ODOT offered contractor Fulsom Construction a bonus to try to make sure the $5 million project is complete before OU football fans take the highway to the game against Texas in October.
Meantime in Carter County, crews are adding special new barriers designed to stop deadly accidents that ODOT says are all too common.
Earp said ODOT is putting up metal barriers around the state, especially where the median is narrow, in order to prevent crossover wrecks.
"Some cars will have a glancing blow on the cable barrier and they're able to drive off and we don't even know who even hits the posts," Earp said.
Crews are also putting in a $3 million bridge on Highway 77 at Hickory Creek in Love County, shutting down the road in that area
Other bridge projects include one at Highway 32 at Coffeepot Creek near Rubottom in western Love County and another on Highway 77 just south of Wynnewood, Earp said.
