I-35E, near downtown Dallas, is back open after two overnight wrecks.
One crash involved a pick up truck that went through a guardrail and landed on Riverfront Boulevard below.
The two people in the truck were taken to a hospital.
A couple hours later, two vehicles crashed on the ramp that connects I-35E to I-30, forcing it to close and drivers to find an alternate route.
No one was hurt in that crash.
In a separate crash, in south Dallas, one car ended up on it's roof and another had it's front end ripped off.
That incident occurred around midnight at the intersection of RB Cullum and Metropolitan.
It's not clear what caused the vehicles to crash, but paramedics rushed two people to Baylor hospital with serious injuries.
