DEA’s bridge inspectors are on-site at the Robertson Tunnel! The 3-mile long Robertson Tunnel is a critical light rail line that connects downtown Portland to the western suburbs in Washington County. Evey two years, DEA inspects TriMet’s Robertson Tunnel over two weeks of night work. DEA has provided bridge and tunnel inspection and preservation services for TriMet Maintenance of Way since 2014.
