The numbered streets of St. Louis, Missouri generally run north–south through the city, starting with 1st Street at the Mississippi River, and increasing in value the further west they are. 1st through 25th Streets are primarily centered around the Downtown and Downtown West neighborhoods, with many extending further north and south into other neighborhoods. There are a few other higher value streets that appear elsewhere in the St. Louis area, and although they are not adjacent to the 1st–25th grid in the eastern part of the city, their numberings in relation to their distances from the river are relatively consistent.
