The Oregon Department of Transportation, Oregon Parks and Recreation Department and other project partners are dedicating the new Mitchell Point Tunnel as part of the Historic Columbia River Highway State Trail on Saturday.  The tunnel segment includes 1.5-miles of the Historic Highway State Trail perched above I-84 and carved through 655 feet of a basalt mountain that overlooks the Gorge.  The new Mitchell Point tunnel is reminiscent of the historic, 1915 tunnel with five arched windows overlooking the Columbia River.  The dedication event offers the public an opportunity to preview the Mitchell Point Tunnel before it opens.  The goal is to complete the work by the end of the year, but the finishing touches on this section of trail are weather dependent and could extend into 2025.  The dedication ceremony begins at 11 a.m. Saturday morning.  Starting from 9:30 a.m., free event shuttles will run from Viento State Park at I-84 east Exit 56 and Columbia Area Transit’s park and ride at 224 Wasco Loop, Hood River.  Shuttles will circulate continuously and will arrive about every 15 minutes.  They are free to ride and there is no parking fee.
