Active Roadways atop of Dams

[Max Rockatansky]

Parker Dam Road carries AZ 95S over the namesake Dam by way of the Colorado River into Earp, California:

Some previous highways that I recall from Arizona was the earliest version of US 80 which crossed Gillespie Dam and AZ 188 which once crossed Roosevelt Dam.

US127 on Wolf Creek Dam Kentucky. Eventually will be bypassed.

You used to go over Hoover Dam before they built a Bypass bridge.

SM-G950U

You can still cross the State Line on the Hoover Dam, you just need to turn around in Arizona.

Well crap, how long ago did US-62 stop running along the top of the Kentucky Dam?

That used to be a favorite route for local truckers wishing to avoid the weigh scales on I-24.

After 9/11. Both the road and the railroad were moved off the dam, I'm told for security reasons.

I have a concrete example which is Brighton Dam Road:

Here are some earthen dams that roads cross:

Here's a local road on a small dam near my home:

Wisteria Drive crosses the dam that holds Gunners Lake.

This one is a park road which crosses the dam that forms Clopper Lake:

TX 22 runs along the dam holding Whitney Lake.  Most of it is on an artificial hill, but part of it is a bridge that runs above the flood gates.  The old route is now along two FM roads and a county road, with part of it in the lake.

FM 310 runs over the Lake Aquilla dam, a small one.  There's no spillway structure, but it looks like there's an emergency spillway that runs over the ground and into a creek.  The water would flood the road if it poured through that outlet to get around the dam.  It looks like the lake has never gotten within 10 feet of that elevation.  The Street View is old.

Not sure if this counts, but there's West Lake Drive (Westchester CR 144) across the Kensico Dam in New York: https://www.eastcoastroads.com/states/ny/west/cr144

It's a road, but it's currently closed to vehicular traffic and only open to pedestrians and bikes.

[SectorZ]

I don't know how many exist in New England, but NH-127 in Hopkinton NH is an active road over a dam.

I swear there are others but for the life of me I am drawing a blank. I know this is probably the closest one to me at a minimum.

Easy. My preferred route to bypass the predatory screw-the-out-of-stater tolls of Maryland and Delaware: US 1 atop the Conowingo Dam.

I live in Harford County, so it's easy for me to go this way to avoid the tolls if I'm going to, say, the Philadelphia area. I went to Staten Island one time and made my way through Cecil County (1 to 273) and took 273 into Delaware, to I-95 and to I-295, where I had to pay the tolls for the Delaware Memorial Bridge and New Jersey Turnpike, but not the Tydings Bridge or the Delaware I-95 toll.

I heard that the Bronx River Parkway was moved off the Kensico Dam for the same reason.

Speaking of the Kensico Dam, as a kid I ran down a steep staircase along the embankment there, and survived! In fact, I didn't even get hurt!

Are you sure it was that long ago?  I could swear I remember driving along the top as recently as 2007.

K-13 over the Tuttle Creek Dam north of Manhattan, Kansas.  K-57 over the Milford Dam west of Fort Riley.

That was the impetus for the change. I can't remember the last time I drove across the dam, if it was before or after 9/11, but I think the project was conceived after that. It would be incredibly surprising for a project of such magnitude to be completed in just six years.

CR 530 in Burlington County NJ goes across the Mirror Lake Dam in Browns Mills NJ, several roads in that town go over dams. that is just the biggest one.

[marleythedog]

I don't know if the dam has a name, but US-40 runs across the Stillwater River dam in Englewood, Ohio (just outside Dayton). The dam creates the reservoir to the north of the road, although the water isn't plainly visible from the road.

That's Englewood Dam. Just a few miles east of that, US 40 goes over the Taylorsville Dam in Vandalia, Ohio, which is on the Great Miami River.

There's five flood control dams in the Miami Conservancy system. Conservancy Rd over Germantown Dam is still open to cars. Huffman Dam is closed to cars (bypassed by SR 444) but has a bike path across it. Lockington Dam Road has been closed for at least 20 years.

NY 21 is on top of the Hornell Reservoir #2 Dam.   Aerial   StreetView

Just around the corner, County Route 57 is on the Hornell Reservoir #3 Dam.   Aerial   no Streetview

PQ-161 is on top of a small dam who control the water flow from Lake Aylmer in St-Gérard (now amalgated to Weedon). https://www.google.com/maps/@45.7604708,-71.4064504,3a,75y,165.96h,100.91t/data=!3m6!1e1!3m4!1sGFQ1qRwBNsobE2kbV8z2Hg!2e0!7i13312!8i6656

KY 1039/IN 101 atop the Markland Dam and Locks near Vevay, IN.
KY 10/OH 253 atop the Greenup Dam and Locks near Greenup, KY.

I've driven across the Frances E Walter Dam not far from the I-80 / I-476 interchange in NE PA:
https://www.google.com/maps/@41.1109763,-75.7201764,3a,75y,309.2h,87t/data=!3m6!1e1!3m4!1shIxSdWTetG15iFOu6g-CUA!2e0!7i16384!8i8192

Every time I cross the Conowingo Dam mentioned above I always think "I can't believe they managed to shoehorn in two travels lanes on this".  No margin for error there.

In the Vancouver, BC area, visited just before international travel was curtailed: Ruskin Dam (the road has been widened since the Street View.)

Stave Falls.

Alabama Route 144 on the Henry Neely Dam.

It's Neely Henry not Henry Neely. According to Wiki, he was an executive at Alabama Power.

Also, just a little further down the Coosa is Logan Martin Dam (near Alpine, AL).

A favorite of mine. Every time I went to Savannah, Tennessee, for my Father's annual family reunion, I would make it a point to visit the Pickwick Dam over the Tennessee River, which was only 10 miles out from the city.

Tennessee Route 128 travels across the top of the dam. Seen here.

Looks like that's built the same way as TN 153 at Chickamauga Dam

Yes, this is one of the few dam/shunpike routes I've taken in my travels. What's interesting (to me, at least), is that I originally planned to shunpike on US-40, on the easy to access route of MD-155 and MD-222. Then I learned that that's tolled as well. But by then, I was so committed to shunpiking that I decided to take the following route, no matter how much extra time it took.



I got groceries in Rising Sun, which I'm sure is something you wanted to know.
