Drivers in northern Wake County will see a slight increase in the speed limit later this month on the 540 Outer Loop.
The state Department of Transportation says it will post new signs bumping the legal limit up to 70mph, from the current 65mph, on a 21-mile stretch of the loop from U.S. 70 near Brier Creek to the U.S. 64 / 264 interchange near Knightdale.
DOT engineers concluded the faster speeds were justified after checking current speeds, crash data and road conditions on the 540 loop.
The Regional Transportation Alliance, a non-profit business group that lobbies for road and transit improvements, had asked DOT to allow the higher speed on 540 and other Triangle-area freeways. DOT said yes last year to faster speeds on Wade Avenue Extension in West Raleigh (60mph) and on from Apex through Sanford (70mph).
