New Hampshire Speedway traffic management

[John F. Carr]

I understand why I never before noticed the crossover used to
allow one southbound lane of I-93 to use the northbound roadway
on race days. The median is made of jersey barriers, but some
of them can be removed. The crossover must be at mile marker 35
where the rumble strips on the inner shoulders vanish.

I got to admire this part of I-93 for 20 minutes last night.
Only one lane was open due to paving and traffic was backed
up. The work must have started at 8 PM, but traffic hadn't
died down enough. They should have waited another hour.

The paving technique is different than Massachusetts uses.
In Massachusetts somebody grinds off the top layer of pavement
across the entire road. The state then waits days or weeks
before gradually applying new pavement. What I saw on I-93 was
one lane that was stripped, cleaned, and repaved in assembly line
fashion.

Yeah, but they still make the same boneheaded decision to repave a
bridge and THEN rebuild the supports by tearing through the pavement to
the understructure.

There was more work found to be needed that originally known before the
construction. Fixing it doesn't seem boneheaded to me.

It is boneheaded, because the repave doesn't go that deep. Plane off
the top two inches of asphalt, spread on the new. Even if, and it's a
BIG if, merely planing off that top layer exposed a deeper problem,
DON'T FRAKING REPAVE IT! Just fix the thing and only after that work
is done, pave the bridge.

The case I'm specifically thinking of is a bridge that's part of a
two-lane road with shoulders almost a full lane wide each. They've
already repaved the entire stretch of roadway, then another crew came
back and are working on the bridge. They've already torn up and
replaced the middle third, and are now working on one of the side
thirds, to be followed by the other side third.
