St. Charles County, Missouri – Frequent travelers of Route 364, also known as the Page Extension, will see welcome traffic relief this fall: additional lanes on the highway in the Mid Rivers Mall Drive area!
Since the opening of Phase III of Route 364 in October 2014, there have been increasing issues with bottlenecks near Mid Rivers Mall Drive. To alleviate traffic, lane construction is a necessity. According to the Missouri Department of Transportation (MoDOT), Route 364 surpassed Interstate 70 (I-70) to become the busiest Missouri River bridge crossing between St. Charles County and St. Louis County during morning and afternoon rush hours. Additionally, the Average Daily Traffic (ADT) count on Route 364 has increased 62.5 percent, from 48,000 vehicles to 78,000 vehicles since the opening of Phase III. St. Charles County Government is a funding partner for this project and has led the effort to get this construction supported and completed.
“Shortly after the Page Extension opened, we knew there were going to be traffic concerns and immediately started working with MoDOT to plan for more lanes,” says St. Charles County Executive Steve Ehlmann. “The traffic counts during the peak hours are three times higher than estimated by the design-build team that constructed 364. We’re happy to report that construction will start soon on this project and the new lanes will be open to the public by the end of the year.”
MoDOT will start construction in July to add the following lanes:
- Route 364 Eastbound:
- Addition of a continuous third lane from the Route 94 on-ramp onto Route 364
- Route 364 Westbound:
- Addition of a continuous fourth lane past the Harvestowne Industrial Drive/Central School Road/Kisker Road existing merge lane (Exit 9) to the Mid Rivers Mall Drive off-ramp (Exit 8B)
- Addition of a continuous third lane past the Mid Rivers Mall Drive existing merge lane (Exit 8B) to the Route 94 off-ramp (Exit 8A)
Traffic disruption during construction is expected to be minimal; any necessary lane closures are scheduled to occur during off-peak traffic times from 9 a.m. to 3 p.m., Monday through Friday. Construction is expected to be complete by November 2018.
The County’s 40 percent share of this $1.2 million project comes from the voter-approved Transportation Sales Tax. This ½-cent tax was enacted in 1985 and reauthorized by voters three times for road improvements that enhance the mobility and safety of our local roads. MoDOT’s share of the project is 50 percent and the City of St. Peters, 10 percent.
