The busy roadway links downtown Matamoros to the highway to Reynosa and a loop which wraps around the city.
Many residents used Twitter to express their frustration with constant gun battles in Matamoros.
"The shootouts always used to happen on Fridays and now they're on Thursdays," wrote on Twitter user in Spanish.
Another Twitter user wrote, "We continue to pray for peace to return to our city."

One resident reported that gun took place in her neighborhood.
"It was horrible," she wrote on Facebook. "There were behind my house."
