I moved out of downtown Houston a little over a year ago. My route to work took me outbound on the 527 elevated which deposited me right on to highway 59 South. So this morning I dropped my mom off at the downtown transit station so she could take the bus to San Antonio. I wheeled over to Smith street which connects to the 527 elevated and as soon as I hit the on-ramp we all screech to a halt. At first I expected an accident but it turned out to just be slow moving traffic congestion. Best I can guess is over the past year GPS wayfinding apps have sent commuters trying to cross downtown off the freeways and through the surface streets. This is an alarming development since the freeways are already completely congested.
