According to the agency, yellow flashing lights are positioned on the northbound lane of EDSA specifically in front of MMDA headquarters, approaching Orense Street, and before Shaw Boulevard underpass. The additional hazard markers, according to the MMDA chairman, were installed on the southbound lane of EDSA particularly at the following areas: before Cubao underpass, approach of Santolan-MRT Station, in front of Megamall approach of Shaw Boulevard-MRT Station split road, approach of Guadalupe-MRT station, and in front of San Carlos Seminary. “We are still planning on where to place the other three units of yellow flashing lights,” Lim said. The agency has installed six units of bollards yellow flashing lights. "Two of those were placed on the northbound lane of EDSA, specifically at Kalayaan and Pioneer. The other four were placed on the following areas on the southbound portion of EDSA: Scout Borromeo, after Santolan-MRT station, after Ortigas MRT station, and after Guadalupe station," MMDA said. The MMDA earlier placed concrete barriers at the left side of the whole stretch of EDSA to separate buses from private vehicles during the period of General Community Quarantine.
