Undetonated explosive devices have been found at the Puente Broncos in Reynosa for two days in a row.
Reynosa city officials reported a “situation of risk” at the bridge around 1:20 p.m. Friday.
Authorities later clarified that an undetonated explosive device had been found on top of the bridge.
One explosive device reportedly detonated at the Gayosso Funeral Home next to the bridge.
It's not clear if any people were wounded in the blast.
Officials are meanwhile asking residents to avoid the area while authorities dispose of the undetonated device.
It’s not clear what kind of device was left but grenades have been left in past cases.
Another undetonated explosive device was left under the bridge around 2:12 p.m. Thursday.
It took authorities about an hour to remove the device and give an all clear signal around 3:18 p.m. Thursday.
Puente Broncos is a nickname for an overpass located next to a baseball stadium for the city’s baseball team, the Broncos.
The roadway links downtown Reynosa to several busy shopping centers and the highway to Monterrey.
Several gun battles and explosive devices have been reported at the bridge since February.
