At Pacific, I-44 widens to six lanes, later to eight lanes. The interstate passes through the suburbs of St. Louis and then into downtown St. Louis, passing the Gateway Arch before finally terminating near the Mississippi River, continuing from there as I-70 from the west end of the Stan Musial Veterans Memorial Bridge. Until a future second span of the new bridge is completed, there will be no way for I-44 traffic to utilize the new Stan Musial Veterans Memorial span without first exiting to surface streets. I-44 traffic wishing to continue northeast and east must use the Poplar Street Bridge and I-55/I-64 to cross the Mississippi River.
