While production continues to film in various locations around Texas, it is also hard at work prepping locations in Detroit and other locations. A example of that is a long ramp that is being built in Detroit on I-375 at Jefferson Avenue. The ramp ends a few feet above street level. A ramp that size is good for one thing - sending cars flying through the air before slamming down onto the highway, probably as part of the "chase from hell." Thanks to J1000 for the info and pictures.
