I’m proofreading the final design draft of my Lincoln Highway Companion book and had to zoom in on Reno. The Truckee River is so narrow through the city that it was missed by the mapmaker. While there I checked on the new and old Reno arches in Street View:
The new arch (built 1987) spans Virginia Street at Commercial Row; the Lincoln Highway passes underneath it.
The old arch was built in 1926 and spanned Virginia Street till 1963; it was rebuilt across S. Lake Street at the edge of the Truckee River and adjacent to the National Automobile Museum.
