Currently, US 21/Boundary Street consists of two 12-foot travel lanes in each direction separated by a single 15-foot two-way left turn lane. The roadway serves approximately 40,000 vehicles per day.
The updated and improved US 21/Boundary Street will consist of two 11-foot travel lanes in each direction separated by a 17-foot raised landscaped median with a sidewalk on the north shoulder and 10-foot multi-use path on the south shoulder.
There will still be a total of four traffic lanes on Boundary Street, two in each direction. In an emergency, three, or even all four of the lanes, can be reconfigured to help people evacuate the area.
