land before entering the city limits of Cottleville. The route curves slightly to the south, crossing over a few roads and interchanging with Gutermuth Road before turning northeast toward Route 94. Concurrency with Route 94 Route 94 joins Route 364 through several miles of suburban developments in St. Charles County after its initial interchange. The freeway widens from just two lanes in each direction to four, and the wide, grassy median is replaced by a barrier. In St. Peters, the route interchanges with Kisker Road and Central School Road immediately after the concurrency with Route 94 begins, and then curves slightly to the northeast where it interchanges with Jungermann Road. The interchanges that take place through St. Peters and part of St. Charles utilize collector-distributor roads to the north and south of the highway, named North St. Peters Parkway and South St. Peters Parkway, respectively. The route then curves northeast, and then back towards the east before interchanging with Woodstone Drive, Harvester Road, Jungs Station Road and Heritage Crossing, all of which are accessed via St. Peters Parkway. After these intersections, the highway briefly enters the St. Charles city limits and interchanges with Route 94 and Muegge Road, marking the eastern end of the concurrency with Route 94. From there, Route 94 turns northeast into St. Charles, while Route 364 turns to the southeast towards the Missouri River. Route 94 to Route 141 South of the interchange with Route 94 and Muegge Road, Route 364 has a diamond interchange with Upper Bottom Road. Immediately after this interchange, the Veterans Memorial Bridge carries ten lanes of Route 364 over the Missouri River, where it enters St. Louis County and the Maryland Heights city limits. The opening of the bridge increased the number of lanes across the Missouri River in the St. Louis metropolitan area from 23 to 33. After crossing the river, the highway descends into the floodplain southeast of the river, through which it continues southeast for a few miles before turning due east and interchanging with Route 141, which at that point is also designated as Maryland Heights Expressway. Route 141 to Interstate 270 East of the interchange with Route 141, Route 364 climbs out of the floodplain via a bridge carrying the highway over the southern tip of Creve Coeur Lake. The ten-lane freeway winds through the Maryland Heights suburbs for a few miles, crossing under overpasses at
