Looks like the definition is key here; BF focused on bridges actually under city jurisdiction, which nets us 5 "city" bridges: "LeForge, Forest, Cross, Prospect, Spring." BF said, "Other bridges within the City limits belong to other jurisdictions (MDOT [I-94, Mich. Ave.?], railroad, etc.)"
cmadler took a more inclusive view, counting ALL the bridges that exist within the city and coming up with 12 or 13. Phew, I had to break out my maps to pin this down and see what's actually within the city limits. Let's take a look (click for larger map image) and boil this down:
- 6 city streets with bridges over the Huron River (Superior, Leforge, Forest, Cross, Michigan, Spring)DD: OK, right off the bat we find that Superior Road Bridge (#1 on the map) is JUST outside the city limits. The section of road leading to the bridge leading to the bridge adjoins the city line, but the BRIDGE PROPER is just BARELY outside of the city. Phew. OK, I'm afraid we'll have to eliminate Superior Bridge.
Leforge Bridge (#2 on the map) actually forms part of the city limit. That's in! Forest (#3), Cross (#4), Michigan (#5), and Spring (#6) are all in. Running total: 5.
- 1 I-94 bridge over the Huron River This appears to be barely within the southernmost city limits and is #7 on the map. Running total: 6.
- Prospect bridge over the railroad just north of Michigan Ave (#8 on the map; also within city limits). Total: 7.
- Michigan Ave bridge over the railroad just inside the city limits Just inside is close enough, #9 on map. Total: 8.
- Grove bridge over I-94 Sure enough--that's one I never thought of! #10 on map. Total: 9
- 2 railroad bridges over the Huron River.The Forest St. bridge (#11) is in. The other one on the northwest side of the city (#12) is, like Superior bridge, BARELY outside the city limits and sadly must be excluded. Total: 10.
- According to Google Maps, "Ecorse Service Road" bridges the Huron River just south of I-94, at the mouth of Ford Lake. I know something bridges it there, but I somehow thought it was just a bike/walk trail. Phew. Dusty D had to delve into Google Maps too...sure enough, there it is, a teeny tiny mini bridge! (#13). Total: 11
But if we're inclusive, then of course we have to throw in the Tridge (#14), totaling 12.
There are a few small bridges within the Washtenaw Country Club golf course, but we'll toss those out as they are not public bridges. Still at 12. (re-scrutinizes map, determined not to miss one!)
Wait!--one more--the Huron going over I-94 is another one that appears to be just barely in/on the city limits! #15 on the list. Total: 13.
There are little bridges at EMU in the Student Center fountain-pond, but they're not really public bridges per se...we'll toss those out too. Still at 13.
Wait! The footbridge linking Waterworks Park with Gilbert Park! Yay! #16. Total: 14.
(feverishly scans map...north, south, east west...)
Phew. I think that's it. So far as I can see, the official total of public foot- and car-bridges within city limits is...14. Thanks to BF and cmadler for their great info!
