JUNGERMANN ROAD BRIDGE REPLACEMENT

Estimated Cost: $2.9 million

Contractor: Pavement Solutions

Engineer: HR Green

Scope: This project will replace two existing deficient culverts on Jungermann Road between Country Creek Drive and Margaret Brown Court. The existing road elevation will also be adjusted to mitigate flooding issues. In addition, improvements will be made to the parks trail to improve safety and access for pedestrians and bikes. The project will include an 11-foot wide trail along Jungermann Road, and construction of two trail crossings at Jungermann Road, one at the Country Creek Drive traffic signal and the other under the new bridge to be constructed just north of Country Creek Drive. This project is eligible to receive more than $1.346 million in reimbursement funding through the St. Charles County Road Board and East-West Gateway Council of Governments.

Currently: Both bridges for this project are complete, and the roadway has been paved. A new barrier wall, fencing and guardrails are being added along the new bridge north of Country Creek Drive. Curb and gutter, a paved trail, and a retaining wall also are being constructed on the west side of the road from Country Creek Drive to Barkwood Trails. Drivers can expect lane closures to allow completion of this work. The overall project is scheduled for completion in spring 2020, weather permitting.
