Route 4 - Portsmouth

A view of the Portsmouth Harbor tugboats on a foggy morning.

Route 4 (A/B) originates in Durham/UNH and services Portsmouth and parts of Newington.

Route 4A leaves Durham, goes to the malls, downtown, the Islington Street corridor, downtown, the malls again, then returns to UNH.

Route 4B leaves Durham, goes to the malls, the Islington Street corridor, downtown, the malls again, then returns to UNH.

The AM Express skips the malls southbound on both the 4A and 4B.

Service Bulletin (posted 10/14): As Spaulding Turnpike construction continues, the Newington Walmart bus stop has re-opened for Portsmouth-bound buses only.  To pick up a bus headed back to Durham, please continue to use the temporary stop at the nearby Texas Roadhouse restaurant.   (The Texas Roadhouse stop for Portsmouth-bound buses is now closed.)
