The engineers of a planned $15.4 million interchange on Interstate 70 have added landscaping to their to-do list.The Warrenton Board of Aldermen approved a deal authorizing engineering firm Crawford, Murphy and Tilly (CMT) to use $52,900 to make the interchange more visually appealing.“It has been determined that we actually have funding to be able to do some aesthetic work,” Director of Operations Terri Thorn told aldermen at their Jan. 17 meeting.“In order to make sure that we have the appropriate aesthetics, we actually need to hire some landscape engineers.”Plans are being developed for fencing and lighting on the interchange’s overpass, “City of Warrenton” signage near the I-70 exits and landscaping at the exit ramps and at three planned roundabout intersections, Thorn said.Drawings of the aesthetics should be available by Jan. 27, she added.The city is looking for low-maintenance landscaping and elements so it appears as “not just a plain concrete bridge,” Thorn said.Plans for long-term economic development in the area will include a requirement for developers to extend the lighting and sidewalks in front of their properties to create an attractive area, she said.“It’s pretty exciting what we will be able to do to make this an attractive western entrance to our city,” Thorn said.The board of aldermen voted to approve the aesthetic agreement 5-0, with Alderman Karen Casserly absent.Landscaping
