Advisory speed limit signs to be removed from I-270
ST. LOUIS (KTVI) – Starting on October 16th, MoDOT will start removing the advisory speed limit signs on I-270. The reason for the removal is that MoDOT will be adding the speed limit advisories to I-270 message boards.
The signs were installed in 2007 to help motorist during times of high traffic volume and warn drivers of slower traffic ahead. Since its inception, the message boards on the the highways have been upgraded, making advisory speed limit sign obsolete. MoDOT says it will re-purpose the signs for other projects.
Advisory speed limit digital signs will be removed in two weeks.
MoDOT believes that between the use of the message boards, 300 traffic cameras, and 400 speed sensors, they will be able to monitor I-270 traffic flow.
