The City of Stillwater had recently implemented a new pavement management program. As the design consultant for one of the program’s initial projects, Lochner prepared plans, specifications, and estimates for pavement improvements in three locations:

  • Monroe Street, from 6th Avenue to 9th Avenue—a distance of approximately 1,200 feet. Lochner’s design plans in this location comprised the replacement of the existing concrete street with new concrete pavement, curbs, and ADA-compliant curb ramps.
  • Walnut Street, from 19th Avenue to 26th Avenue (2,630 feet), and 19th Avenue, from Western Road to Walnut Street (2,470 feet). Lochner’s design plans for these two stretches of roadway replaced the existing asphalt pavement with concrete pavement. The roadways retained their open channel drainage.
  • The intersection of 7th Avenue and Duncan Street. Lochner designed full-depth pavement reconstruction and added ADA-compliant ramps at this intersection. The roadway width was narrowed to deter speeding.

In addition to design, Lochner provided the City with bidding assistance and construction support for the project.
