Mill Creek Bridge, a single-arch stone bridge constructed in 1873, carried SR 0191 over Mill Creek and was an important part of the Lower Mill Creek Historic District. Its construction reinforced the importance of the Newfoundland Turnpike as a regional transportation route and ensured both the Haag and Robacker mills access to customers and markets. Built of stone with sidewalls and wing walls of course rubble ashlar, the bridge had a semicircular arch with dressed stone voussoirs that spanned 24 feet and rose about 20 feet above the creek. The structure was approximately 65 feet long and about 25 feet wide, including the parapets, and carried two 10-foot-wide travel lanes. In 1934-35, the mid-nineteenth-century structure was widened on the downstream eastern side to its present width of approximately 25 feet, requiring partial reconstruction of the arch and relocation of the east sidewall and wing walls. It was eventually replaced because of severe physical deterioration and roadway deficiencies.
