US 281 - 1604 Interchange:

This view is looking south at the US 281/Loop 1604 interchange. The southern end of the project is shown with four new direct connector ramps on the north side of Loop 1604, which make it possible for southbound US 281 motorists to go from freeway lanes directly to eastbound or westbound Loop 1604; likewise, Loop 1604 motorists have direct access to US 281 freeway lanes heading north. Motorists travelling north on US 281 pass underneath Sonterra Boulevard just as they do today, then have the option of using free access lanes, freeway lanes, or a managed lane to continue their trip north. US 281 motorists travelling south also pass underneath Sonterra Boulevard and continue their trip south on freeway lanes or free access lanes, just as they do today.
