The Lehigh and Northampton Transportation Authority (LANTA) is a regional public transportation authority that provides public bus and rapid transit service throughout the Lehigh Valley region of eastern Pennsylvania, including Allentown, Bethlehem, Easton, and their respective suburbs.

[4] LANTA was founded in March 1972 in response to meet growing public transportation needs in Lehigh and Northampton.

The solution was to create a bi-county, municipal authority that would operate all public transit services in the two counties.

[5] LANTA is governed by the Lehigh and Northampton Transportation Authority board, which has ten voting and two non-voting members appointed by county executives.

Seniors, through a state lottery funded program, were offered free fare access during off-peak hours and weekends in 1975.

The Authority's main service is in the urbanized area of Allentown, Bethlehem, and Easton and surrounding Lehigh Valley boroughs and townships.

This included a color-coded route information system to make riding transit more user-friendly.

Fully accessible vans are available through contracts with private operators to take people to destinations door-to-door for a higher, zoned fare.

On October 21, 2001, LANTa began offering Sunday bus service to further increase access to public transit.

The service is funded through revenues from the farebox, a grant from the Pennsylvania Lottery program with revenue generated by rides taken on the system by seniors 65 and older, grants from Lehigh and Northampton counties, the Pennsylvania Department of Transportation, and the Federal Transit Administration.

Combined these grants pay approximately 60% of the cost of operation; the remaining funds come through the lottery program and passenger fares.

The agency has grown in more recent years, adding more and more bus routes throughout the Lehigh Valley.

In August 2011, a new LANtaBus system was introduced that changed the route naming scheme from letters to one-to-three digits.

The Night Owl service runs late-night from Center City Allentown to Lehigh Valley Hospital–Cedar Crest.
