I don't think I posted this 2 years ago when it was released. I just ran across it the other day and don't remember watching it before. It gives an excellent rundown of all parts of the new I-74 bridge project, along with the entire I-74 corridor changes. That includes what's now being done at the 53rd Street interchange. The video also confirms that the actual bridge will be 4 lanes in each direction. Talk about a change for the better!
