Get ready for the next round of confusing traffic tie ups and detours in Jefferson City. Crews will shut down several on and off ramps as part of the Highway – 54 / Missouri Blvd project beginning next Tuesday. The westbound 54 off ramp to Missouri Blvd, the eastbound 50 ramp to 54 and the Missouri Blvd ramp to eastbound Highway – 50 will close. Traffic through the work zones has been especially bad as traffic to the Lake has created long jams.
