Portland will close the Eastbank Esplanade for two months starting Feb. 1, in what marks one of the most extensive maintenance projects in the popular trail’s nearly 20 year history. Mark Ross, Portland Parks and Recreation spokesman, said the $500,000 maintenance project includes repairing concrete on the esplanade, installing new and improved lights, cleaning out trash and painting over graffiti, removing dead trees and planting additional trees and native plants.
