Frontage roads are quite useful, but the near-complete lack of cloverleaf ramps in Texas is maddening. You can't just smoothly flow from a freeway to a surface

Frontage roads are quite useful, but the near-complete lack of cloverleaf ramps in Texas is maddening. You can't just smoothly flow from a freeway to a surface street, which means you're always having to hit traffic signals. 610 at Westheimer in Houston is a perfect example of all that going completely wrong.
