Urban Infrastructure Design
Depending on state law and the functional classification of a roadway, the authority and
responsibility for the design of local roadways may rest with a local government. It is recog-
nized that some state DOTs (West Virginia, Virginia, and a few others) have authority over
local roadway design. Federal and most state roadway design regulations are intended to
accommodate trucks. Unfortunately, in some cases older roadways and bridges and local road-
ways do not meet these design standards (see Exhibit 5-4). Older urban intersections, narrow
streets, and alleyways may restrict truck mobility causing trucks to hit poles or signs located
on corners or to drive over sidewalks to make turns. In some urban areas, trucks entering a
railyard, port, or other private-sector intermodal facility must travel through privately owned
parking lots and local facilities over old urban roadways that are difficult to negotiate. Out-
dated or insufficient infrastructure design can impact urban freight mobility and access to
buildings and facilities and result in
· Increased congestion: The additional time trucks may require negotiating turns, avoiding low
bridges, and so on may result in congestion and backups on the roadways.
