From Washington D.C. all the way to California, this bridge will bridge the gap, all 4,000 feet of it. It's certainly not just a structure though, Project Manager Kip Hall, showed us that it's so much more.

"The other thing that makes it very unique is the network tied arch system here is the largest in the world, that's something special for both Ohioans and West Virginians, something to hang their hat on," says Hall.

It connects both states, in Ohio about 50 feet of the bridge sits over the river, but each state requires different water drainage.

"Over in Ohio, it's fully contained, any water that comes off the deck proceeds down into a pipe, none of it will actually drop onto the ground, it will drain into the river. In West Virginia, it's an open scupper drain, so when it comes out, it drops down wherever it comes out," says Hall.

It was an elaborate and expensive project, so it's no surprise they included features to protect the structures quality, from cars and animals.

"The screen that you're looking at is a bird screen, it's there to keep the corrosion down because we've discovered through what birds do naturally is very corrosive to the structure. So, we're taking care of this structure, we went to the lengths of putting up bird screens to make sure they don't build their nests there," says Hall.

To restore wildlife on Blennerhassett Island, they will plant 6,000 new trees right under the bridge. Hall says when the trees are fully grown it will look like the bridge was meant to be among the trees all along.
