Expect brief delays crossing the Robert O. Norris Bridge this Friday between 9:00 a.m. and noon. Traffic will be reduced to a single lane on the bridge to allow crews to perform routine maintenance work. Automated flagging assistance devices will direct one-way, alternating traffic through the work zone, assisted by a flagging crew. The work is weather permitting.
