The Tyler Transit changed to a two bus hub structure a few years ago for its five lines; four meet downtown (210 E. Oakwood ST) at the central offices/train museum, and three meet at the Bergfeld Shopping Center (9th & Roseland). Tyler, TX is a rectangular city with most of its territory considered to be South Tyler. These are the five Tyler bus lines: Red (north-south), Blue (west), Green (east), Yellow (southwest-southeast), and Purple (north-south with east jog to Hospital District, aka. Midtown). https://www.cityoftyler.org/Departments/TylerTransit/MapandSchedules.aspx
The four bus lines at downtown are Red, Blue, Green, and Purple. Purple doesn’t go further north than downtown–unlike the other three. Thus, only three of the five bus lines run in small North Tyler: Red, Blue, and Green. The Red Line goes to the northern edge of the city. The three bus lines at Bergfeld Shopping Center–six to 13 minutes south of the Transit Depot–are Red, Yellow, and Purple. The Yellow Line doesn’t go further north than the Bergfeld Shopping Center. The Blue (west) and Green (east) Lines don’t meet at that southern hub. The Yellow Southwest goes to FRESH, an upscale branch of Brookshire’s Grocery Store. The Yellow Line Southeast goes to University of Texas at Tyler. The Green Line unites all three colleges: Texas College (north), Tyler Junior College (east-central), and UT-Tyler (far southeast).
The Red and Purple Lines usually run parallel to each other on Broadway–Tyler’s major street: a north-south street that runs its entire length. The Red Line’s southernmost point is the Carmike Shopping Center, while the Purple Line’s southernmost point is the new Cumberland Shopping Center in far south Tyler at the intersection of South Broadway and Loop 49. The Purple Line is the newest transit line in Tyler. It includes a twist to the east down E. Houston Street to S. Beckham–where the two hospitals are located–followed by a turn on E. 5th back towards the center of the city.
To conclude, the bus hub transit structure of Tyler, Texas makes sense because it’s a rectangular city with most of its land in the south. A circular city would benefit from one big hub in the center. I was motivated to write this article as a response to a friend’s nostalgia for the one bus hub era.
