Route 33 western terminus at the traffic circle in Stratham, where it meets Route 108
NH 33 begins at the Stratham Traffic Circle where it meets NH 108. The route travels northeast, passing by Stratham Hill Park and curving to the east before crossing into the town of Greenland. NH 33 meets the northern terminus of NH 151 near the town center, then the highway bends to the northeast and enters the Portsmouth city limits.[citation needed]
NH 33, which is initially Greenland Road upon entering Portmsouth, passes the southern entrance to Pease International Tradeport then interchanges with Interstate 95 at a partial cloverleaf interchange (exit 3) and continues to the east, becoming Middle Road. NH 33 crosses over US 1 Bypass without an intersection before terminating at the intersection of Middle Road and Lafayette Road/Middle Street (US 1).[2] US 1 provides local access to US 1 Bypass to the south.[citation needed]
NH 33 is poorly signed in downtown Portsmouth.[citation needed] The last eastbound and first westbound markers for NH 33 are at its intersection with Islington Street approximately 1 mile (1.6 km) west of US 1. NH 33 is unsigned from both Middle Street and Lafayette Road, and no other guide signs are present in the downtown area.[citation needed]
History
The entirety of NH 33 was once the easternmost section of NH 101. In October 1994, NH 101 was re-routed along the former NH 51 from NH 108 in Stratham to Hampton Beach. At that time, what had been NH 101 from the Stratham Traffic Circle to its eastern terminus was designated as NH 33.[3]
