Low clearances

[Bruce]

Mullen Road in Lacey, WA has a 12-foot bridge under a major railroad. Apparently it has a few fans:

This one is fun, mostly because its completely decorative, and only to dissuade big vehicles from entering that parking area

MSP Airport says hi (er, low)

What is the lowest known clearance on a major arterial or busy highway? I know there is the 10'-9" overpass in Syracuse on Onondaga Lake Parkway (which remediating would be very difficult due to the water table, parkland and ownership issues). Any that are lower?

No way that only has ten feet of clearance...

In the other direction, it's 12 feet.

I managed to catch this while on Storrow Drive eastbound just two days ago (January 31st) just before the Kenmore / Fenway exit, three bridges from the above link. Box truck in front did clear the 11 ft bridge successfully and got off at the Kenmore exit, otherwise, the driver would have struck the 10ft0in bridge three bridges after that (Next bridges are 12, 11 then 10 ft (ped overpass + tunnel) at the Copley Square exit).

A 9 footer in my neck of the woods.  Yes, its a road for cars:

Drove through this on a drive through Williston, ND in its boom town days about 10 years ago.  Thought it had a low clearance sign, but can't find one in GSV anywhere.  This connects 6th Ave W with Riverside Drive.  At the time, it was something of a bypass before the US 2/US 85 intersection was improved -- that intersection backed up terribly with all the trucks loading and unloading in the town.

What's remarkable there is that it appears people have gone around the low clearance, over on the left.

So, people do read signs...except on the Onondaga Lake Parkway.

What I want to know is why was the road built at the only point where the clearance is low.

My favorite local "low clearance" bridge - and also "narrow clearance" - one car at a time! BNSF at 4th Street in Mendota, IL

I've never found an explanation for that in the research I did on both rail crossings of the Kings River in Reedley.  To your point you'd think that the Southern Pacific wouldn't want Ag trucks near the support structure of their trestle.

Wonder how many people have completely ignored the clearance itself and the signage for it.

Two of my favorites in NY...

https://maps.app.goo.gl/GP9EYBnC9cpyHLij9 - 7'9" on Gower Road for a one-lane tunnel under a railroad, a bit west of Scotia, NY.

https://maps.app.goo.gl/1CDrWSQNwdTDuxTG7 - 4'11" on the right shoulder of the WB Grand Central Parkway, for an arch bridge under 69th Road. While I've seen arch bridges elsewhere with different clearances for different lanes, this probably takes the cake for both the lowest signed clearance and the biggest difference between parts of the same overpass (10'4" in the left lane vs. 4'11" on the right shoulder vs. not even marked, but definitely higher, in the center lanes). At least this one's on a highway that does not allow trucks.

I'm amazed the GSV car fit under that, with its camera mount.

3 m clearance on Crewson's Line under the railway parallel to Highway 7 near Acton, ON

[catch22]

This is West Grand Boulevard in Detroit, with 8' 10" clearance underneath the railroad south of Michigan Avenue.  Back in the ancient times before freeways, this was a lot busier than it is now.  It was the quickest path to the Ambassador Bridge from the west side (W. Grand to Porter to the bridge entrance).
