The Missouri Department of Transportation (MoDOT) will lower the speed limit from 50 to 45 on a mile and a half of Route Z in St. Charles County near .
MoDOT recently evaluated traffic speeds on the route. The department found that drivers were traveling slower between Interstate 70 and Perry Cate than on the remaining portion of the roadway. The speed limit reduction complements an ordinance recently passed by Wentzville, lowering the speed limit on the mile and a half section of Route Z.
“This section of Wentzville has grown extensively,” said Jim Gremaud, St. Charles County area engineer. “We have seen an increase in traffic along that portion of Route Z and expect to see even more due to Wentzville’s future expansion of Interstate Drive and the growth projected around Interstate 70. That increased traffic and potential additional entrances on Route Z required a lower speed limit.”
Crews will start putting new signs along the corridor starting March 7. Installation should take about a week. The new speed limits will go into effect after the new signs are installed and uncovered.
