What is the longest highway exit ramp. The ramp at the US 30/US 250
interchange west of Wooster OH is almost 1-1/2 miles long. It's really
Route 85 connector from I-290 to Rte 85 in Hudson, MA.
Damn, I checked. Only 1.7 miles ling.
I think that the Route 85 Connector is "officially" an unnumbered Mass.
state highway, not a ramp.
One I probably mentioned long before this topic became almost old enough
to vote is Exit 1 SB offramp from US 3/Everett Turnpike. Despite being a
standard diamond configuration, it is about a mile long. The intent was
to prevent access between Exit 2 and Exit 1, the reason being planned
tollbooths, I believe. (they were never built). They later added short
ramp-to-ramp ramps to allow access between Exits 1 & 2.
Also Exit 2 itself may be considered a long ramp, to NH 3A in Hudson.
Also about a mile long, with a sub-exit to Daniel Webster Highway. This
is actually the only part of the planned Nashua Circumferential Highway
that was ever built.
The whole ramp complex there (Exits 1 & 2) has strange 2/10 mile markers,
with the Everett Turnpike symbol and a number of the form R2-B instead of
a route number. I haven't seen similar ramp mile markers anywhere else in
NH. The number after the R must be the associated exit number (1 & 2 for
Exits 1 and 2) and the letter is for the individual ramp roadway.
