Camp Street is a 17-block street that had aging infrastructure resulting in significant drainage problems for this County State Aid Highway (CSAH 152). In addition, there were extensive safety concerns caused by a deteriorating retaining wall and steep roadway sections that limited driver sight lines.
Due to a narrow right-of-way of only 44 feet on portions of the street, vertical and horizontal realignment of this roadway would be difficult to achieve for this urban reconstruction project.
Camp Street Improvements
St. Louis County and the City of Ely both hired JPJ Engineering to oversee the design and reconstruction of this $2.5M road improvement. Due to the limited spacing, JPJ Engineering worked closely with the county to procure numerous temporary easements.
The existing stone retaining wall was replaced with a modular block retaining wall. To improve drainage and sight lines, JPJ Engineering designed an extensive storm sewer system that involved the drilling, blasting and excavation of approximately 1,500 cubic yards of ledge rock.
