RALEIGH — Lane closures will be in effect this weekend on westbound Interstate 440 east of downtown Raleigh for improvements to the bridge across Atlantic Avenue and CSX Railroad tracks.
Closure of a single traffic lane and the inside shoulder lane between the Wake Forest Road and Capital Boulevard exits is necessary to allow work crews to safely remove about 1 1/4 inches of the existing concrete bridge deck and replace it with latex modified concrete.
Single lane and inside shoulder closures will be in place throughout the weekend from 9 p.m. Friday, Nov. 16, through 5 a.m. Monday, Nov. 19.
Concrete pouring requires closure of a second traffic lane and will be done overnight. The additional lane will be closed from:
• 9 p.m. on Friday until 9 a.m. on Saturday;
• 10 p.m. on Saturday until 11 a.m. on Sunday; and
• 9 p.m. on Sunday until 5 a.m. on Monday.
The latex modified concrete will reduce infiltration of water and salt below the roadway surface, extending the life of the pavement longer than regular concrete and improving the ride quality for motorists. It is also sets and hardens faster, allowing for a quicker re-opening of the bridge lanes, which is important on a heavily-traveled road such as I-440.
The work is part of a $2.3 million contract awarded for preservation work on this bridge and for the U.S. 64 east and westbound bridges over I-440 east of downtown Raleigh.
Resurfacing with latex modified concrete can substantially extend the life of a bridge at a cost significantly lower than continually repairing or replacing the bridge. It is part of the NCDOT’s $430 million bridge plan for 2011-12, which calls for preservation, repairs or replacement of 450 bridges statewide.
NCDOT reminds motorists to watch signs for construction information, stay alert and obey the posted speed limit.
