Valentine Corporation is starting work on the installation of additional drainage improvements for the 70 Irwin Street slide repair project on Monday. This will include 750 feet of v-ditch and approximately 1,000 feet of asphalt berm adjacent to the location of the slide. This work will take approximately 2 months to complete and will require one lane traffic on Irwin from 121 Irwin to Rose Lane during weekdays. Full access will be provided week nights and weekends. The Department of Public Works will post local traffic only signs during the duration of the construction.
