Duello Road - Phase 3A

The project reconstructs 0.33 miles of Duello Road starting approximately 400 feet north of Orf Road and ending at Route N where construction currently is taking place to relocate Hopewell Road and realign Route N to reduce hazardous curves. Proposed improvements include:

  • Widening Duello Road and adding curb and gutter and enclosed storm drainage.
  • Smoothing vertical alignment for improved sight distance.
  • Constructing ADA-compliant concrete sidewalks along both sides of the roadway.
  • Adding northbound and southbound left-turn lanes and a westbound right-turn lane at the intersection with Orf Road.

The project is funded by St. Charles County’s ½-cent Transportation Sales Tax and with Federal Highway Administration (FHWA) Surface Transportation Program-Suballocated (STP-S) funding. The engineering design consultant is Great River Engineering (GRE), and the project is estimated to cost approximately $2.9M.
