Highway 90 has not always been the main source of travels, until 1940 when it was built and took the place across the bridge across the Medina River. That and the fact that they were pretty much isolated for the last fifty years. Many of the original buildings still stand today. With some renovations and remodeling they have since been converted to shops, houses, and Texas Historical Markers for tourist to view. Some of the buildings have been converted into antique shops, which Castroville is also famous for.
Today there are more than ten antique shops in the town.
There are antique shows annually in April and September for tourist and visitors to view. Castroville has retained most of its Alsatian culture through its annual celebrations and holidays. Even there are only two police officers on duty at a time, they manage to patrol the twenty thousand vehicles that pass through the town on Highway 90 each day. Other than Highway 90 the only other main way into town is the town airport. The airport is located two miles East of Castroville, towards San Antonio.
