The dry run on Friday morning for the implementation of the so-called Zipper Lane along two southbound lanes of EDSA resulted in heavy traffic congestion that stretched up to Roxas Boulevard.
This is based on the monitoring of the Metrobase of the Metro Manila Development Authority (MMDA).
The dry run was enforced from 9:30 am to 11:30 am.
The activity brought a lot of confusing to motorists.
Huge traffic jams were observed for over an hour.
Zipper lane allows southbound motorists to use the innermost northbound lane of EDSA from Main Avenue in Cubao to Edsa-Ortigas flyover located across Guadix Drive-MRT Ortigas.
The scheme will be fully enforced next week during week days beginning Monday (January 23).
It aims to benefit motorists heading straight to Makati City.
U-turn slot in the middle of EDSA across Camp Crame and the flyover ramp from EDSA to Ortigas Avenue to Greenhills will be closed and motorists can use the right service roads.
