With the State Hwy 54 Expressway scheduled to open by the end of the year, you may want to prepare for some name changes. MoDOT will call the expressway State Hwy 54, in line with the eastern stretch that’s already open. The existing 54, west of the Grand Glaize bridge will be renamed Osage Beach Parkway. Starting January 1st, Osage Beach Parkway will become the official name for all addresses west of Grand Glaize bridge on Hwy 54. The City of Osage Beach’s sent letters to all those who’ll be getting the new street name, and asking them to change their addresses on all printed materials by January 1st.
