Historic endpoints of US highway 4 in Portsmouth, NH

Photos credits: Serdar Kaya; Dan Moraseski

US 4 was commissioned along with the original routes of 1926. At the time, it ended in Portsmouth, most likely downtown. I haven't seen a map that pinpoints exactly where, but we know US 1 was routed along State Street. My best guess is that US 4 traffic was directed to come in on Maplewood Avenue, jogged around a bit, ended up on Pleasant Street, and terminated at its junction with US 1 at State. The shot below shows that intersection:

That's looking south on Pleasant, which is one-way northbound today. But it was probably two-ways originally, and it's possible that US 4 came down this way and ended at the intersection in the middleground (State, or US 1).

The following research is courtesy of Dan Moraseski. He writes:

"In 1940, a bypass for US 1 was built around Portsmouth Center, and US 4 was realigned or cut back to end at it."

Before we continue, you may find it helpful to refer to a modern map of that part of the city:

USGS, most recent

US 4 now ends at the rotary in the center of the map, but it once ended just north and east of there: it used to be routed on the road that goes past St. Catherine Church (Woodbury Avenue).

In the map below, you can see US 4 coming in from the upper left; it ends at US 1 near the label for Christian Shore:

"The following photos are of this location; it is not clear if the interchange is original or was built in 1950."

This first one shows the signage heading southeast on Woodbury Avenue at BYP US 1 (once mainline US 1) at the former east end of US 4:

To the right are connections with I-95 and the Spaulding Turnpike, or modern US 4; interesting how that's signed only as NH hwy. 16 but not US 4.

Also, you have to go right, then loop back around (behind the camera and to the left) to go north on BYP US 1.

Below, we're heading the opposite direction (northwest on Woodbury) at BYP US 1. (Likewise here you have to go left and then loop back to the right to go north.) Straight ahead was once the east beginning of US 4.

The green signs in the distance are shown close-up below:

Below are photos from old US 1 (now BYP US 1) at the former east beginning of US 4; this first one is from northbound...

...and the shot below is from southbound BYP US 1:

Moraseski, Jan. 2003

"Between 1941 and 1956, US 1 was moved back to the old (and current) route and the bypass became BYP US 1. The New Hampshire Turnpike (now I-95) was built in 1950. This tied into BYP US 1 just south of US 4 (modern I-95 heading into Maine wasn't built until later). In 1956 (I think), the Spaulding Turnpike was built. US 4 was moved onto it. A rotary (Portsmouth Circle) was built (probably in 1950) at the intersection of the two turnpikes and BYP US 1."

USGS, c. 1956

"From 1970-1972, current I-95 bypassing and north of Portsmouth Circle was built (see most recent map above; features in purple are relatively recent revisions). Previous to that, I-95 traffic used BYP US 1 between the NH and Maine Turnpikes. Direct ramps from both directions of I-95 to US 4 west and US 4 east to I-95 south were built; traffic from US 4 east to I-95 north still has to use Portsmouth Circle but it is a right turn. Around 1992, NH 16 was moved onto the Spaulding, so US 4 and 16 both end at the same interchange. So US 4 has ended at Portsmouth Circle since probably 1956."
