A yearlong project beginning Monday to repair the Historic Columbia River Highway's Crown Point viaduct will cause lane closures, traffic delays and a three-month closure of the historic Vista House.
The project includes repairing deteriorating support columns on the 600-foot concrete viaduct and repaving 3 miles of the highway between Larch Mountain Road and Latourell Falls and is intended to enhance safety during travel on the highway and visits to the circa 1918 house.
