close that down to make it an excess point to hot lanes they are still developing. they know it's going to take time for drivers to get used to the changes it's bringing. >> this is a permanent change. drivers are used to making the left exit. the benefit to this is instead of all the weave and traffic jockeying to the right and the slowdown it creates, we think by having the right exit, it will help with traffic flow at this interchange. >> reporter: these walls are going to help you. they are going to shift these walls over to the left. where i'm standing now, this construction area, this is going to be where traffic will be flowing tomorrow. you are going to be moved toward the right hand lanes if you are trying to get on to 66 from i-495. again, this is all going to
