municipalities to pass resolutions opposing the freeway. A petition to put the freeway up for referendum was submitted in 1998, and enough signatures were collected to force a vote. On November 3, 1998, voters approved right-of-way for the freeway by a 61% margin, and construction continued. In exchange, St. Louis County accepted of land adjacent to the park. Current developments On February 17, 2020, work began on a new interchange with Gutermuth Road, roughly 2 miles west of the western end of Route 364's concurrency with Route 94. Situated between the Route 94/Mid Rivers Mall Drive and Route K exits, a gap that spanned nearly four miles, the new exit would provide direct connections to residential Cottleville, alleviating significant traffic burdens on roadways between those two exits. The interchange, given the exit number 6, opened on the evening of November 19, 2020. In early March 2021, construction began on slip ramps connecting Heritage Crossing. The ramps will connect to westbound 364/94 and from eastbound 364/94 via North and South St. Peters Parkways, respectively. The new slipramps opened on August 10, 2021. In October 2021, MoDOT awarded a contract to update the interchange between Route 364, Route 94 and Muegge Road in St. Peters, and construction began in November. The current interchange does not offer direct connection from Muegge Road to westbound Route 364/94 or to eastbound Route 94. The updated interchange aims to fix this by constructing a diverging diamond interchange at Muegge Road. Construction is slated to be finished by spring 2023.
