The Metropolitan Manila Development Authority (MMDA) said the Expanded Number Coding Scheme will remain in effect on Monday as President Ferdinand Marcos Jr. delivers his fifth State of the Nation Address (SoNA).

The agency said about 500 personnel will be deployed along Commonwealth Avenue and nearby roads to manage traffic, enforce road-clearing operations and respond to medical and emergency incidents.

“For traffic management, road clearing, plus our medical and emergency personnel, there will be around 500 of us in the area,” MMDA general manager Nicolas Torre III said.

The MMDA earlier advised motorists to take alternate routes, warning of heavy traffic along Commonwealth Avenue, IBP Road and other major thoroughfares surrounding the Batasang Pambansa Complex.

Torre said the agency is also considering implementing a zipper lane along Commonwealth Avenue, subject to a traffic assessment on Monday.

The MMDA said U-turn slots in front of UP Technohub and Tandang Sora along Commonwealth Avenue have been temporarily closed from Sunday through Monday at the request of the Quezon City Police District.

Meanwhile, the Quezon City government said zipper lanes will be opened from Elliptical Road (Philcoa) to Sandiganbayan and from Doña Carmen to IBP-Litex to facilitate the movement of government officials and guests heading to the Batasang Pambansa Complex.
