MoDOT is adjusting the speed limits on portions Route 54 and Osage Beach Parkway, between Linn Creek and Osage Beach in Camden County, to maintain consistent speed and traffic flow through the area. Between Route Y and the new expressway, the speed limit on U.S. 54 increases from 60 to 65 m.p.h. … making the speed limit 65 all the way to Bagnell Dam Blvd. in Miller County. The speed limit on Osage Beach Parkway changes from 50 to 45 m.p.h. between Key Largo Road and El Terra Road, to match the remainder of the parkway. The changes are taking effect today and tomorrow, as weather conditions allow crews to install the new speed limit signs.
