Groundbreaking for the Viaduct Rail Park was held on October 31, 2016. The contractor, AP Construction, immediately began to clear the site, removing overgrown trees, shrubs and debris. Construction fences were erected as site clearing continued while awaiting final soils and other environmental reports. In the last few weeks, the contractor has removed much of the ballast on the trestle itself in order to allow for cleaning, waterproofing and sealing the top side of the bridge structures that pass over city streets. Lead abatement will follow on the underside of the bridges, before they are repaired, repainted and relamped.
