Main Street Faces Whatever Brought The Town

Old commercial streets are not laid out at random. A main street faces the thing that brought people, and the building fronts point at the town's original reason.

Water towns face the landing

Settlements founded on river and lake traffic put their business fronts toward the water, because that is where goods arrived and where customers stepped ashore.

Warehouses sat closest, with retail behind them, so the grade from the landing upward often still shows a change from heavy structures to shopfronts.

When river traffic collapsed, those towns were left facing an empty waterfront, and many turned their backs on it for a century before rediscovering it.

Railroad towns face the tracks

Where a line arrived first, the depot became the center, and the commercial street ran parallel to the rails with its fronts toward the platform.

Elevators, stockyards and lumber dealers took the trackside, since they needed direct siding access, and that industrial strip separated the business street from whatever lay beyond.

The distinctive result is a town with a clear front and back, where one side of the tracks accumulated the trade and the other did not.

Courthouse towns face inward

County seats laid out around a square face the courthouse rather than any route, because the business drawn to town was legal and administrative.

Merchants competed for frontage on the square itself, and the corner positions were the most valuable because they caught traffic from two directions.

These towns often survived economic changes better than trackside towns, since the county's business continued regardless of what happened to freight.

Highway towns face the road

Settlements that grew with automobile traffic front the highway, and their commercial buildings sit back behind parking because the customer arrives in a vehicle.

That setback is the visual break between older and newer American commercial building, and it appears wherever a town expanded after cars became ordinary.

When a new alignment bypasses the town, the frontage loses its purpose immediately, which is why bypassed strips empty out faster than historic cores do.

Towns often carry two orientations at once

Many places were founded on water, rebuilt around a railroad and then extended along a highway, leaving three commercial districts of different ages and geometries.

The districts usually do not line up, and the awkward angles where they meet are the most legible historical evidence in the town plan.

Reading those angles gives a sequence of events without any archive, since each street grid was laid out square to whatever mattered at the time.
