Lendal Bridge stands on the site of a former rope-ferry where the city walls break for the River Ouse.
The bridge connects two medieval towers: Lendal Tower on the east bank and Barker Tower on the west bank. It was designed by civil engineer Thomas Page, who also designed London's Westminster Bridge. It is made of cast iron, and has a single span of 175 feet.
The bridge opened in 1863. Together with the attached tollhouses it is a Grade II listed building. Link
Lendal Bridge links Station Road with Museum Street and thus York railway station with York Minster, and is part of York's Inner Ring Road.

The A1036 runs 8 miles from Copmanthorpe to Hopgrove via York.

Listed buildings and structures are officially designated as being of special architectural, historical or cultural significance. There are over half a million listed structures in the United Kingdom, covered by around 375,000 listings.
Listed status is more commonly associated with buildings or groups of buildings, however it can cover many other structures, including bridges, headstones, steps, ponds, monuments, walls, phone boxes, wrecks, parks, and heritage sites, and in more recent times a road crossing (Abbey Road) and graffiti art (Banksy 'Spy-booth') have been included.

In England and Wales there are three main listing designations;
Grade I (2.5%) - exceptional interest, sometimes considered to be internationally important.
Grade II* (5.5%) - particularly important buildings of more than special interest.
Grade II (92%) - nationally important and of special interest.

There are also locally listed structures (at the discretion of local authorities) using A, B and C designations.

In Scotland three classifications are also used but the criteria are different. There are around 47,500 Listed buildings.
Category A (8%)- generally equivalent to Grade I and II* in England and Wales
Category B (51%)- this appears generally to cover the ground of Grade II, recognising national importance.
Category C (41%)- buildings of local importance, probably with some overlap with English Grade II.

In Northern Ireland the criteria are similar to Scotland, but the classifications are:
Grade A (2.3%)
Grade B+ (4.7%)
Grade B (93%)
