The Bonnington Aqueduct is an aqueduct on the Union Canal, to the west of Edinburgh, Scotland.
History
The original aqueduct was {{convert|10|ft}} in diameter.{{cite book|title=Concrete and Constructional Engineering|url=https://books.google.com/books?id=cQnOAAAAMAAJ|year=1928|publisher=Concrete Publications|page=82}} The present aqueduct is a concrete replacement, opened in 1978 to allow the road beneath to be widened.{{cite book|last=Fleming|first=George|title=The Millennium Link: The Rehabilitation of the Forth & Clyde and Union Canals|url=https://books.google.com/books?id=X9XmZQZB0pIC&pg=PA30|year=2000|publisher=Thomas Telford|isbn=978-0-7277-2945-3|page=30}}
Design
The canal and the roughly parallel M8 motorway pass over the B7030 Cliftonhall Road.{{cite web |url=http://canmore.rcahms.gov.uk/en/site/50794/details/union+canal+ratho+aqueduct/ |title=Union Canal, Ratho Aqueduct |publisher=rcahms.gov.uk |accessdate=29 December 2014}}{{Google maps |url=https://www.google.com/maps/@55.9248501,-3.4148351,220m/data=!3m1!1e3 |title=Bonnington Aqueduct |accessdate=29 December 2014}} The aqueduct is only the width of a single boat, meaning that boats may have to wait to pass. Just to the east of the aqueduct, the canal broadens and there is an island with a bird shelter.
On the canal, the aqueduct is located between Bridge 15 (Ratho Bridge) and Bridge 16 (Nellfield Bridge).
The aqueduct is named after the village of Bonnington to the south, near the border with West Lothian.
