This summer three projects are under construction to improve fish passage. The projects will impact travel on Latigo St. SE, Littlerock Rd. SW and Houston Dr. NW.
On Latigo St. SE, a 88-foot span, two-lane bridge will be installed starting in late June. Drivers can expect delays as the road will be reduced to a single-lane bypass controlled by flaggers to alternate traffic. For bikers and pedestrians, the Chehalis Western Trail near Latigo St. SE will also be reduced to one lane where additional railings will be installed to complete previous bridge work.
Work to construct a 16-foot-wide box culvert under Littlerock Rd. SW near Sargent Rd. SW will start in early July. Drivers can expect delays as travel will be reduced to a single-lane bypass road controlled by automated signals to alternate traffic.
Crews will begin construction on a 12-foot-wide box culvert under Houston Dr. NW in early August. Drivers can expect delays during construction as traffic will be limited to one lane.
Work at all locations is scheduled to be completed in October.
Fish use streams throughout the county to return to their upstream spawning habitat. Each of these roads has a culvert under it which channels stream water in a way that blocks fish passage.
