Work on the planned diverging diamond interchange at Interstate 77 Exit 28 in Cornelius has been delayed until early January, Town Manager Anthony Roberts said Friday.
Blythe Construction of Charlotte intended to begin demolishing concrete islands on Catawba and West Catawba avenues this week, but workers would be unable to pave the road due to recent low temperatures, Roberts said.
A diverging diamond intersection allows two directions of traffic to temporarily cross to the left side of the road while on the bridge. Once on the left side of the road, vehicles can turn left onto the I-77 ramps without stopping and without conflicting with through traffic.
That makes such interchanges far safer than traditional interchanges and less traffic-clogged, transportation officials have said.
At least 30,000 vehicles a day travel Catawba and West Catawba avenues at the prime Lake Norman exit, town officials said.
The $6.2 million project will take about 1 1/2 years to complete; it’s one of several diverging diamonds planned or under construction in the Charlotte area.
Blythe will do much of the Exit 28 work at night, which the town requested to lessen the impact on businesses and motorists.
