- The N.C. Department of Transportation
will take a major step forward this weekend in the construction of Greensboro's first diverging diamond interchange, which will link High Point Road to I-73 as part of a $40.1 million project to widen a four-mile section of High Point Road from two lanes to four lanes with a median.The diverging diamond interchange is unique because it allows traffic moving in two directions to temporarily cross to the left side of the road, moving a high volume of traffic through the intersection without increasing the number of lanes and traffic signals. This innovative design will allow motorists to easily access I-73 from High Point Road and will prevent the congestion and crashes that can occur when vehicles back up on interstate ramps. Motorists will see the diverging diamond interchange beginning to take shape as crews set the bridge girders over I-73 North this weekend, weather permitting. The work will require crews to close I-73 North near I-85 at 10 p.m. on Friday, Oct. 11 and is expected to be complete by 6 a.m. on Monday, Oct. 14.During the closure, motorists on I-73 North will take U.S. 220 North to I-40 West as a detour route. Motorists on I-85 North will use Business 85 North to U.S. 220 North to I-40 West. Motorists traveling to Winston-Salem and points west are encouraged to take Business 85 South to I-40 West. A map of the various detour routes can be seen here.For real-time travel information at any time, call 511, visit www.ncdot.gov/travel or follow NCDOT on Twitter at www.ncdot.gov/travel/twitter.
