JOHANNESBURG - Expect delays if you’re making your way to OR Tambo International Airport.

Metered taxi operators are protesting against Uber, which they complain is not registered to operate.

Police said the protest which affected R21, R24 and N12 highways, was illegal and metered taxis would be removed and those involved arrested.

What gives ANYONE the right to restrict YOUR movement thanks to a failed and dated business plan? #AntiUberStrike pic.twitter.com/dyWqdqBycx — Cliff Pinto (@PigSpotter) March 10, 2017

There was congestion on R21 as people tried to Kempton Park and beyond to Pretoria.

Ekurhuleni Metro Police are advising motorists to use alternative routes to Tshwane and OR Tambo International Airport

EMPD spokesman Kobedi Mokheseng said they are closely monitoring the go-slow.

"Your alternative routes if you are at the Gilooly’s Interchange heading towards east either with R24 or N12, you’ll proceed straight direction east with the N12. At the off-ramp at Driefontein Interchange, take the R21. That will take you north if your destination is Tshwane or the OR Tambo International Airport.”

Mokheseng said his department is working together with Gauteng Traffic Police, SAPS and other law enforcement agencies to monitor the situation.
