Pontcysyllte Aqueduct work will be a tall order
The iconic Pontcysyllte Aqueduct is closing for some high level work.
The Thomas Telford-built bridge, which soars 125 feet over the River Dee, will be partially sealed off for the next month.
The scheduled maintenance means closures until Friday February 9.
The aqueduct will be closed to pedestrians at all times and will be closed to boats Monday to Friday 9am to 3pm. However it will be open before and after these times during daylight hours and will remain open on Saturdays and Sundays.
The Canal and River Trust will carry out work to ensure the structure and the Llangollen Canal that crosses it continues to be in good order.
The world-famous aqueduct and canal attracts about 300,000 visitors a year and a consultation is under way to help bring in more people, with a development that would include a new visitor centre.
The bridge was constructed under the instruction of Telford between 1796 and 1805.
