I never see a speed limit sign on I-270. How noticeable will these signs be?
Currently, there are 38 speed limit signs on I-270. This project will nearly double the number of signs (to just under 70). Drivers will see a speed limit sign nearly every mile along the route. Additionally, MoDOT is installing speed limit signs along the median (in between eastbound and westbound lanes in both directions). This is a first for the St. Louis area along interstates.

How distracting will these signs be?
These signs will look practically the same as other speed limit signs, except that the number will be allowed to be changed. A defensive driver, who is paying attention to the road, should be able to pay attention to the speed limit signs, important messages on the overhead message board, his or her speed, as well as paying attention to the other drivers on the road.
