What this tracks
This dataset records the locations and identifiers of overhead gantry structures along Nevada highways, primarily used for traffic monitoring or signage.
Why it matters to you
These gantries often hold speed cameras or electronic signs that display traffic alerts. Knowing their locations helps you anticipate speed enforcement zones when driving through Nevada, especially on I-15 near Tropicana Avenue. Trucking companies can use this to plan routes avoiding frequent enforcement areas, while commuters can check for congestion alerts before heading home.
