The Union Street Undercrossing in The Dalles will remain closed to all traffic.  The Dalles Public Works Department says flood waters have receded from the underpass, but the road section remains “super saturated,” and will need a drying period of seven to ten days to avoid damage.  Union Street northbound remains closed to through traffic at the railroad tracks, and remains completely closed north of the Hattenhauer access road.  Access to Lewis and Clark Festival Park will be open throughout the drying period.  Approaching the undercrossing from the west side, West First Street will be closed to through traffic at Terminal Way and will be completely closed beyond the Oregon Cherry Growers facility employee access.  Motorists are encouraged to continue using Webber Street as an alternate route to access West First Street during the undercrossing’s closure.
