A shoulder rumble strip will be installed by the state Department of Transportation on I-84 in Danbury this weekend. The work is being done between Exits 8 to 9 in Newtown, Bethel, Brookfield and Danbury. Motorists can expect lane closures eastbound and westbound from 7pm to 5am Sunday into Monday the 13th. The project consists of milling the concrete to add a shoulder rumble strip. The DOT says modifications or extensions to the work schedule may be necessary due to weather delays or other unforeseen conditions. Motorists are advised to maintain a safe speed when driving in this vicinity.
