City of The Dalles crews and contractors next week will apply fog seal to all streets that received chip seal treatment last month. These fog seal projects will require short duration road closures between 7:00 a.m. and 5:00 p.m. at each location. Detours will be in place during work hours. A complete list of streets involved is available at thedalles.org. Fog sealing is an asphalt emulsion sprayed on to a pavement surface. The emulsion is diluted to a proper consistency to obtain complete coverage of the roadway, and extends the life of chip seal treatments.
