The avenues were then numbered consecutively to the north, even where they began to deviate from the diagonal grid, so that 27th Street meets 26th Avenue in the Five Points intersection. They are also extrapolated north of the grid, beyond Denver's main northern border at 52nd Avenue to 168th Avenue at the border between Adams and Weld Counties. Avenue numbers are also extrapolated south from Colfax to First Avenue. Ellsworth Ave is the 00 point, and south of here avenues are named.
