Understanding Manchester's geography
Why Manchester's drive times defy radius math.
The Merrimack River bisects the metro and limits east-west crossings to a handful of bridges, meaning a 10-minute radius from Elm Street may not realistically reach the eastern residential neighborhoods across the river. I-93 to the north opens strong access toward Hooksett and Concord, stretching isochrones northward.
Bedford to the southwest along Route 101 is the highest-income suburb and fastest-growing commercial corridor in the metro — franchise operators targeting affluent households should anchor near the South Willow Street retail strip, which captures both Manchester and Bedford traffic.
