Heading up to Warren today I decided to take a different route. Ended up taking Mt. Elliott up to Mound. Driving there I noticed the massive high bridge running over the railroad tracks. Seemed way too big for Mt. Elliott- I was expecting a dinky underpass like Conant. Could it possibly have been designed to carry Mound Road's expressway? Davidson extension? Was proximity to then-busy City airport? As always, interested to hear your thoughts. Thanks.
