DHMC, others to pay portion of road upgrade Modified: 3/31/2021 10:20:17 PM LEBANON — Plans to upgrade a heavily trafficked intersection near Dartmouth-Hitchcock Medical Center would see the hospital and nearby property owners split planning and construction costs over multiple years. But the burden won’t be evenly applied to all. The hospital — which owns 10 properties within an assessment district proposed by city planners — would be on the hook for more than 83% of the price tag for projects that will cost at least hundreds of thousands of dollars. Officials say that’s because the majority of drivers passing through the intersection of Mount Support Road and Lahaye Drive are on their way to and from DHMC.
