"This experimental project involved placing a waterproof membrane, PavePrep(tm), and a 0.15 ft. thick plant mix overlay on the deck of the existing Two Medicine Bridge. This was to preserve the deck from further deterioration and maintain an adequate riding surface until replacement of the bridge by the year 2005. This project is located on NINHS N-1, US-2 approximate milepost 210 in Glacier County on the Blackfeet Indian Reservation."
