The Spaulding Turnpike is a freeway in eastern New Hampshire. Its southern terminus is at the Portsmouth Traffic Circle (Interstate 95 / U.S. Route 1 Bypass) in Portsmouth, a terminus it shares with U.S. Route 4 and New Hampshire Route 16. Its northern terminus is at an interchange with New Hampshire Route 125 in Milton, where NH 16 continues north as a full-access highway. The Turnpike roughly parallels the Maine border. In the mid-1990s NH 16 was signed onto it. The Turnpike is part of the New Hampshire Turnpike System operated by the New Hampshire Department of Transportation Bureau of Turnpikes. Along with I-95 between the Massachusetts state border and the Portsmouth Circle (Blue Star Turnpike), the two turnpikes are collectively known as the Eastern Turnpike. ==Route description== The Spaulding Turnpike begins in Portsmouth, at I-95 northbound exit 4. Access from I-95 south and US 1 Bypass is facilitated via exit 5 (Portsmouth Traffic Circle). A northbound-only exit connects with Brady Drive, accessible only from the traffic circle. The Spaulding Turnpike becomes a six-lane freeway concurrent with US 4 and NH 16, with a speed limit. Exit 1 in Newington provides access to Pease International Tradeport and the Newington malls. The Turnpike currently narrows to 2 lanes in each direction just north of exit 1. Exit 2, a northbound only exit/entrance which facilitated access to The Mall at Fox Run and adjacent businesses, was closed permanently on July 16, 2015. Exit 3, a southbound exit/northbound entrance connecting to Woodbury Avenue, was closed in summer 2015 and is being constructed into a full-access interchange with a connection to Pease Tradeport via Arboretum Drive. The new exit 3 is slated for opening in October 2015. Exit 4 provides access to Newington Village and industrial areas along Shattuck Way. The Turnpike then crosses the Little Bay Bridge into Dover. Exit 5 (currently closed for construction, scheduled to reopen in late 2015) provides access to Hilton Park and Wentworth Terrace. This exit will also be permanently closed in 2018 as part of a reconstructed exit 6 interchange. US 4 leaves the Turnpike at exit 6 (Dover Point Road), with the Dover barrier toll located just to the north. Currently there is no access from eastbound US 4 to the northbound Turnpike, nor from the southbound Turnpike to Dover Point Road north. Exit 6 is scheduled to be reconstructed in 2018 to allow for full access in all directions, including connections to Hilton Park and Wentworth Terrace.
