All lanes of Highland Road at Interstate 10 in Baton Rouge will be closed for 10 consecutive nights, from August 20 through August 30, to accommodate nighttime construction work.
The closures are necessary to install steel girders over Highland Road to support a new bridge that is part of the I-10 On the Greaux widening project. Highland Road, also known as La. 42, will be closed between the interstate on-ramps and off-ramps from 9 p.m. each night from August 20 through August 30 until 5 a.m. the following morning.
The closures may cause some drivers to take alternate routes. Westbound I-10 drivers who want to travel on Highland Road toward LSU should take the next westbound exit, Siegen Lane. Eastbound I-10 drivers who want to travel on Highland toward Airline Highway should take the next eastbound exit, La. 73.
Both of the existing interstate bridges above Highland Road will be replaced with one larger bridge to hold six lanes of traffic. The Aug. 20-30 girder installation is for the the middle portion of the new bridge. Once the middle portion of the new bridge is completed, all I-10 westbound traffic will be diverted onto the new section. This should occur near the end of 2018. Other steps in the building of the new I-10 bridge at Highland:
- Once westbound I-10 traffic is diverted to the new section, crews will remove the existing westbound bridge and build the westbound portion of the new bridge, which will be tied in with the newly created middle section.
- When the new westbound portion is completed, it will carry all westbound traffic, and eastbound traffic will be detoured onto the middle section of the new bridge.
- During this time, crews will remove the old eastbound bridge and complete construction of the new bridge.
- Once completed, the new bridge over Highland Road will have three 12-foot travel lanes in each direction, 10-foot outside shoulders and 19-foot inside shoulders separated by a two-foot barrier.
