By the time you spot the picturesque Casselman River Bridge, you're almost in Grantsville. This single-span stone arch bridge ½ mi east of town was built in 1813; at the time it was the largest of its kind. Though the bridge is no longer in use, it serves as the backdrop for a small state park and picnic area.
