 The reconstruction of MD 231 was completed from Prince Frederick to Hallowing Point in 1956 and from Hughesville to Benedict by 1958.The Benedict Bridge remained the southernmost crossing of the Patuxent River until the opening of the Governor Thomas Johnson Bridge between Solomons at the bottom of Calvert County and California in St. Mary's County in 1978.The "functionally obsolete" bridge underwent major repairs in 2002, during which the bridge was reduced to one lane of traffic in alternating directions.
