President Dwight D. Eisenhower killed Highway 99.Can Clark County commissioners resurrect it? Commissioners are getting ready to adopt a detailed plan for improving the dog-eared thoroughfare that lost its power after Eisenhower signed off on the interstate system in the 1950s. Interstate 5 replaced Highway 99 as the main north-south corridor linking big cities along the West Coast because Highway 99 did not meet federal guidelines for an interstate.For details on the Highway 99 Sub-Area Plan, click hereNow, commissioners are hoping a new set of guidelines and development incentives will, over the next few decades, improve upon what has been described in public comments as “an eyesore,” “inconvenient” and “messy.”Commissioners will consider adopting the Highway 99 Sub-Area Plan following a final public hearing at 10 a.m. July 13 at the Public Service Center, 1300 Franklin St.If adopted, the plan will go into effect Aug. 1.The plan has been years in the making and reflects input from business owners and neighbors. It targets Highway 99 from the Chelatchie Prairie Railroad Bridge near Northeast 63rd Street up to Northeast 134th Street. Colete Anderson, a county planner who has served as project manager for the past four years, said Thursday that commissioners ranked Highway 99 and the surrounding area as a “focused public investment area.” The county’s currently working on, for example, a proposed sports complex on Northeast 78th Street near St. Johns Road and redoing the county’s old poor farm into the 78th Street Heritage Farm. Elements of that plan include a trail system with viewpoints and signs, energy-efficient greenhouses, continued community and food bank gardens and a parking area that might host a farmers market.
