(1) Due to conversion from English to metric units and to rounding, individual cell values may not agree with corresponding mileage table cell values. May see differences from prior years; starting in 1999, number of lanes is coded for all systems except rural minor collector and rural/urban local.
Please note that due to data review and production issues with the 2021 HPMS data, some anomalous and/or missing data may exist.

(2) Rural minor collector and rural/urban local functional system lane miles estimated by FHWA assuming two as the number of lanes.

(3) 2020 Data.
