The Bangkok Metropolitan Administration (BMA) and the Metropolitan Police Bureau (MPB) will enforce traffic changes in the Rattanakosin area, starting next Monday.
Three measures will be enforced over a 60-day trial period to boost road safety and improve traffic flow on narrow streets in the area, said BMA spokeswoman Threedow Aphaiwongs.
One-way traffic will be enforced on Phra Sumen Road between Bang Lamphu and the Sipsam Hang T-junction and on Tanao Road between Khok Wua and Si Kak Sao Ching Cha intersections.
Vehicle speeds will be limited to 30km/hour on Phra Sumen, Tanao Road, Din So, and Bamrung Muang roads.
Parking will be prohibited on Phra Sumen Road, between Bang Lamphu and Sip Sam Hang intersections from 5am to 9am, and on Tanao Road from 3pm to 8pm every day, and from Kok Wua to Si Kak Sao Ching Cha from 6am to 8pm every day except Sundays.
Parking will be forbidden on Tanao Road, from the Kok Wua intersection to the canal bordering Wat Mahan Pharam.
Pol Maj Gen Adul Narongsak, deputy chief of the MPB, warned traffic violators will face fines during the trial period.
