Monthly Construction & Environmental Project Updates

June 2016

West End (SR 79)

  • Construction safety zone in effect along SR79. Speed limit reduced to 45 mph.
  • Traffic remains re-routed over the completed section of new roadway.
  • Section of culvert west of SR79 completed (western half of culvert). Slopes remain stabilized with permanent vegetation, Rolled Erosion Control Products (RECP), and wattles installed at culvert walls and slopes.
  • Eastern half of culvert construction began in January. Expected completion date of culvert to be late July. Remaining northbound roadwork and paving will be done after culvert construction is completed. Exposed areas covered with plastic sheeting or hay mulch.
  • New ditch lines on east side of SR79 that drain north and south of new culvert remain stable with RECP and wattles.
  • Several layers of new asphalt have been placed on north bound roadway at both south and north ends of SR79. Some slope and roadwork between ramps remains to be completed.
  • Three Step Pool conveyances near Green Drive along Self Creek have been completed and the disturbed areas remain stabilized with permanent vegetation and RECP.
  • Sediment basin slopes remain stabilized with permanent seed and RECP.
  • Perimeter controls remain in place along stream to protect water quality.
  • Sediment Retention Barrier (silt fence and hay bales) remain at Self Creek.
    Sedimentation Basins (with pumps and skimmers) on SR 79 functioning properly. Active Stormwater Treatment applied as necessary to discharge clean water.
  • General items: Site mowing of all permanent vegetation has been completed.
    Completed ramp slopes are stabilized with permanent seed and RECP. Completed ramp roads are now “capped” with aggregate. North Access Road and cul-de-sac at Old TN Pike have been paved.
