2020 Street Construction & Improvements Project:
The project generally consists of a full reconstruction of the roadway on Arthur Street, George Street, William Street, Olof Street, Henry Street, Charles Street, and the westernmost portion of Valparaiso Avenue; along with slurry sealing of the three public parking lots in the downtown area. Work on the project began on September 1st with Team Ghilotti, Inc. (TGI) potholing to locate existing utilities on each of the streets to be repaved; followed by the replacement of ramps, sidewalk, curb and gutter at various locations throughout the project and digouts in the public parking lots. The slurry sealing operation of the public parking lots is tentatively scheduled for mid-October.
The City has elected to perform a full depth reclamation (FDR) on each of the project streets. Generally, the FDR process consists of grinding and pulverizing the entire existing roadway and underlying materials to a certain depth, mixing in cement and other agents then recompacting to solidify the recycled materials as the new roadway base, then finishing up with paving of the new asphalt section. The FDR method of roadway rehabilitation is a robust treatment, and will produce a high quality and long lasting product (20-25+ year useful lifespan). TGI began the FDR operation on September 28th, and anticipates finishing the roadway paving by October 9th. The work is anticipated to run through mid to late November for full completion of the project. We appreciate your patience and understanding during any inconveniences which may be caused by the project. If you have any questions or concerns, please do not hesitate to give us a call.
