Ingersoll Avenue Reconstruction

Ingersoll Avenue Reconstruction

Des Moines, IA

McClure was selected to perform a Corridor Evaluation Traffic Study from Polk Boulevard to 42nd Street along Ingersoll Avenue in the City of Des Moines to comply with the City of Des Moines’ Complete Streets Policy and meeting current traffic and parking needs. As part of the study, McClure performed traffic data collection, traffic forecasting, reviewed multimodal transportation needs, parking analysis, developed corridor improvement alternatives, evaluated each alternative, and provided a recommendation for improvements.

Based off the studies recommendations, McClure performed the design that included complete pavement reconstruction with buffered bike lanes, on-side street parking with permeable pavers, ADA compliant sidewalks, driveways, cement treated subgrade, storm sewer, subdrain, water main, retaining walls, stairs, traffic signal upgrades, and erosion control. Additionally, multiple temporary easement acquisitions and plats were developed. Project coordination with multiple key stakeholders, Des Moines Area Transit (DART) and Des Moines Water Works, was critical to the project success.
