A section of the Riverfront Trail in The Dalles will be closed through Tuesday to accommodate construction work that began today. Northern Wasco County Parks and Recreation District Executive Director Phil Lewis says the trail near mile marker 2 is being lowered by seven feet to accommodate the unloading of large transformers into the Celilo converter station off of Highway 97. The trail will receive an asphalt overlay to allow continued use, and will be returned to its current elevation at the end of August. The trail should reopen on Tuesday. There will be four dates when the trail will be closed for transport of the transformers, with the first on April 1, and additional dates falling in 30 to 45 day sequences.
