Highway 133

Home » Guides » North Carolina » Highway 133

NC 133 is a coastal route originating at Caswell Beach in Brunswick County. The state route crosses the Intracoastal Waterway north to Brunswick County Airport and NC 210 near Southport. Prior to 2016, the two highways combined east for 0.80 miles to Dosher Cutoff SE. Opening at that time was a 3.4-mile realignment along Long Beach Road Extension. The two-lane road bypassed Dosher Cutoff SE and shortened the overlap with NC 87 north out of Southport for NC 133. Work on the $22 million contract ran from May 2013 to May 2016.1

Additional work starting in 2019 will add a grade separation between NC 133 at NC 210. The new overpass will be built as part of an $85 million project to expand N.C. 211 east from Midway Road to N.C. 87 at Southport.2

NC 133 combines with NC 87 for one mile north to River Road. NC 87 branches northwest to Boiling Spring Lakes while NC 133 shifts eastward alongside Sunny Point Military Ocean terminal and the Cape Fear River. The state route continues along River Road to Belville and a diverging diamond interchange (DDI) with U.S. 17/74/76 opposite Village Road and Leland. The exchange opened to traffic on April 15, 2016 and was built during the Causeway Bridge Project underway from January 27, 2014 to November 15, 2016.3

Heading east toward Wilmington, NC 133 navigates along a series of overlaps, starting with U.S. 17/74/76 across the Brunswick River. The state route accompanies U.S. 74/421 north from U.S. 17/76 over the Cape Fear River to Martin Luther King, Jr. Parkway, an expressway spanning the Northeast Cape Fear River into Wilmington. U.S. 74/NC 133 overlap east 1.8 miles to Hightsville, where NC 133 shifts onto Castle Hayne Road north.

NC 133 combines with U.S. 117 from Castle Hayne northward across the Northeast Cape Fear River into Pender County. The two split 1.78 miles beyond the county line at Marlboro, with the final 3.90 miles of NC 133 extending west to NC 210 between Rocky Point and Long Creek.
