South Dakota Department of Transportation uses new technology in construction project near Sioux Falls
Crews are working to repair the concrete on I-29 northbound from south of 26th Street to south of Exit 86, which is the Renner and Crooks exit. The first portion of the project has the three lanes on the interstate reduced to two from south of the 26th Street exit to north of the 12th Street exit.
Travis Dressen with the Department of Transportation said he is using an advance queue detection system on the project to warn drivers of the construction zone. This means there are speed sensors scattered throughout the project that are connected to digital message boards. For example, as cars drop below the speed limit of 45 mph due to congestion, the message boards warn of slowed traffic ahead and reduced speeds. This technology is fairly new to South Dakota with construction projects, but it has been used during the Sturgis Rally out west.
The project costs $3.1 million and has a completion date of November 17, 2017. Dressen also wanted to warn drivers to be sure they are wearing their seat belt, obeying the speed limits and planning their trip accordingly with slight delays.
