Kameni most preko Zagorske Mrežnice u Oštarijama sagrađen je tijekom francuske vladavine Ilirskim provincijama od 1809. do 1813. godine. Ime je dobio po Napoleonovom maršalu Augustu Marmontu, upravitelju Ilirskih provincija. Most je s kosim silaznim prilazima dug 92 metara i ima 12 lučnih otvora. Od 1959. godine pruža se preko suhog korita Zagorske Mrežnice, čija je voda preusmjerena za potrebe hidroelektrane Gojak na Dobri. Obnovljen je nakon 1998. godine.
