The Route 1 and I-95 Improvements at Exit 126 project includes widening US 1 from four to six lanes between the ramps to I-95, adding a left turn lane from US 1 onto I-95 southbound, and adding a left turn lane from US 1 onto I-95 northbound. On I-95, one lane northbound will be added from the US 1 on-ramp to Courthouse Road (Route 208). Noise barrier walls along I-95 southbound will be constructed for a length of approximately 4,700 feet.
