The intersection of Edgcumbe Road and St Paul Avenue will be closed for construction through the end of July 2023. This closure is longer than anticipated because of a number of unforeseen challenges, including:
More rock excavation than expected. Soil borings indicated rock at a depth of 4.5’, which would have allowed installation of catch basins and pavement without rock excavation. In some areas, the rock was actually closer to 2.5’ deep, which requires rock excavation.
Special equipment is needed to perform certain work in the bedrock. The specialized subcontractor and equipment will be available the week of July 5.
Diesel Range Organic (DRO) contaminated soils were uncovered and removed. Soil borings before construction did not indicate any contaminants, nor did the MPCA website indicate any past spills or underground storage tanks (USTs). This was an isolated area. In accordance with the MPCA, any petroleum laden soils must be separated, protected, and tested. Testing and identification of an appropriate disposal site took 7 days in itself.
The city and the contractor are working to complete the entire reconstruction of Edgcumbe Road by October 31. Please keep in mind that construction timelines are tentative and subject to change.
Thanks for your continued patience and cooperation.
