The roof on a Highway 7 toll gate collapsed in heavy rain, but avoided injuring anyone.
Transport Minister Saksayam Chidchob ordered an urgent investigation by the Highways Department after the Aug. 1 collapse at the Bangpakong first and second toll gates in Chachoengsao.
About 10 minutes after the 10:35 a.m. collapse, local highway-maintenance crews blocked off the scene to avoid accidents.
