To strengthen the retaining wall to the Colne Brook at the eastern side of Mill Street, Colnbrook (located at NGR 502831,177145).
The carriageway next to the retaining wall is the only access road for the adjacent properties, the wall which supports the carriageway and facing the brook has suffered damage due to a considerable amount of overgrown vegetation and tree roots.
This wall requires partial reconstruction, and total of 6 trees need to be removed. The trees have destabilised the foundation which was supporting the wall, and if not repaired will lead to a collapse at anytime.
Prior to commencement of the works, Slough Borough Council needs to obtained the approval from Environment Agency for the diversion of the water course in order to carry out this work. Following a consent received from the Environment Agency to protect the fish and the flooding caused by high rainfall event, we need to build the temporary dam using sandbag headwall.
The bridge replacement works was completed on 19 June 2019. Below are the photographs of the bridge, taken before and after the completion.
"The result is excellent. In keeping with the existing wall and very well made." Read the full email here.
Windsor Meadows Footbridge (Structure No. 1829, located at NGR 495510, 179510) connects residential areas Ruby Close to Coe Spur.
The Windsor Meadows Footbridge carries a footpath over a small stream near Ruby Close in Slough. It is a single span, timber footbridge comprising two longitudinal timber beams, transverse timber bracing and transverse timber decking. The stream flows from north to south. The span is approximately 9.9m in length and the deck width is approximately 1.8m.
The primary timber beam on the north side was significantly decayed along the top section with fungus evident on the inside of the bridge and the parapet infill bars having fallen into the river due to vandalism. This has resulted in loose deck boards that are not firmly affixed to the main beam, and could either become completely detached or at least cause a trip hazard to the public. There was only parapet mesh between vertical parapet posts, approximately 1.2m apart.
Therefore, vertical infill bars was re-attached between the parapet posts to protect public safety as a temporary measure.
The bridge replacement works, which were funded by the Department for Transport’s recent pothole funding to repair roads and structures, were completed on 29 March 2019.
