Yes, now I remember. I saw him couple of years ago somewhere near Springfield.

I even took a photo on the rest area:

I-376 Pittsburgh, PA

This bridge is finally being demolished. It spans I-376 in Pittsburgh. They built a bridge structure underneath it to protect motorists from falling debris.

Interesting. It seems to me that in most places, such demolition work is done at night with the road below closed. Much less expensive than building a temporary bridge structure underneath. Is this sort of temporary protective structure used elsewhere?

Maybe because of the height of the bridge, the debris would have damaged the road itself? keokiracer answered this question as I was adding it. Thanks keokiracer!

The temporary bridge wasn't built because of the demolishing of the bridge, it was built because the bridge was literally crumbling onto the road beneath. And instead of demolishing the bridge immediately they built a bridge underneath the bridge to catch falling debris...

Efficiency!

Indeed. I don't know when the bridge-under-the-bridge was built, but Google Earth shows it in its imagery as far back as 2004!

I recently read a novel about a spy story set in the early Cold War era (1948).
At one point it mentions a police chasing along the Interstate 95 between New York and Washington.
How is this possible? AFAIK the Insterstate system was introduced during Eisenhower presidency, in the late 1950s. Is this a hystorical inaccuracy due to poor research by the writer or that freeway already existed in 1948, maybe not called interstate 95?

It's an inaccuracy. It's an interesting one, though, in that in attempting to fix it you learn a lot about some of the US' oldest highways.

While there was no direct highway between DC and NY immediately after WWII, plans were already afoot for one. In fact, the end-to-end mainlines of the Maryland, Delaware, and New Jersey Turnpike predate the Interstate Highway Act entirely in conception.

The NJ Turnpike's mainline was built 1950-53 and is tied for the oldest part of the highway system (note that it bypasses Philadelphia completely). Its completion was soon followed by that of the Delaware Memorial Bridge's first span; both of these predate Interstate designation.

At the time of the Act, the Delaware Turnpike (from the DE Memorial Br to the MD state line) was being planned; the decision was made to designate it I-95. Note, however, that I-95 deviates from this mainline between Christina and Trenton (it would have been extended along its own alignment up to New York). One suspects that this is due to a fair amount of pressure from Pennsylvania's representatives, to make sure Philly wasn't bypassed completely.

The Baltimore-Washington Parkway (mostly maintained by the NPS), built between 1950 and 1954, ties the NJ Turnpike for the oldest segments opened, although the former was completed first. However, Maryland spent almost all of its allocated money on the Baltimore and Washington beltways, and so had no money to complete its part of the Turnpike system. Like the Delaware Turnpike, it was incorporated into the Interstates, but unlike in Delaware, it was less a matter of convenience and more a matter of the state needing to raise money to built it.

Maryland's part of the NY-DC highway wasn't built until 1962-63, a full decade after the rest of the highway had opened. Delaware's section (other than the Delaware Memorial Bridge approaches) was built at the same, largely because its main purpose was to connect to the MD Turnpike. After Kennedy's 1963 assassination, the Maryland and Delaware turnpikes were renamed the John F. Kennedy Memorial Highway.

While at Pittsburg, where the hell is "The West" ? Such a british road sign
(Britain's M1's and M6's signs all pointing to "The North" Anywhere between London and Scottland pointing northbound)

I kind of have a reason:

I-76 bypasses Youngstown to the south, then heads through Akron, and finally ends at I-71 in the middle of nowhere. Continuing to follow I-71 will indeed lead you to points west. "West" can therefore be read as a directional in lieu of a strong control city; the problem is that the best control city -- Cleveland -- is on I-80, which would probably require three signs on the gantry:

- I-76, Akron and points west
- I-76 to I-80, Cleveland
- I-376, Pittsburgh

I think by West they mean, beyond Cleaveland, like Toledo, Detroit, or even Chicago

Forget that, the best control city ever is other Desert Cities .

What he said.

Just to add that the reason the John F. Kennedy Memorial Highway got that name is that JFK had cut the ribbon just a week before he was killed.

But yes, there was no such thing as an "Interstate" in 1948 and would not be for nearly a decade. And little if anything in the way of freeway between New York and Washington.

I take it as "Ohio and points [farther] west." It's preferable to the usual Pennsylvania practice, which would be to assume the world ends at Youngstown.

(Which reminds me, when Chrissie Hynde (sp?) of the Pretenders sang "I went back to Ohio and my city was gone," she was talking about Akron.)

Between the two roadways are rest areas and the NC Vietnam Veterans' War Memorial. The roadways cross over so that anyone wishing to visit the memorial doesn't have to take a left exit coming or going (onto a freeway which usually sees speeds well over 80 mph).
