 US 30 / US 67 head east along Lincoln Way and ascend 50 feet ( 15 m ) onto a plateau , atop which reside stores and restaurants . As they continue east , the two routes split into one @-@ way streets , eastbound Liberty Avenue and westbound Camanche Avenue . The one @-@ way street alignment ends at 11th Avenue South , but quickly begins again as US 30 / US 67 turn to the north onto northbound South Third Street and southbound South Fourth Street . At Eighth Avenue South , US 30 splits away from US 67 and onto the Gateway Bridge and crosses into Illinois .
