The B9143 runs along Inchyra Road in Grangemouth, connecting the A904 and A905 to the south of the town centre. It is almost entirely industrial, starting at a roundabout in the shadow of the cooling towers and buildings of the vast petrochemical refinery complex at Grangemouth. The road then heads south west in a dead-straight line along a tree-lined avenue, passing more industrial sites and the Grangemouth Stadium, beyond which are some blocks of flats and lower level residential development. The terminal roundabout on the A905 is soon reached.
History
This road barely even existed in 1960, being just a track across fields at the northern end. However, as the refinery grew, so did Grangemouth as a whole, and so this road became increasingly important as a distributor route within the town. Although the full chronology is not clear, the 1974 OS One Inch and 1976 Landranger maps shows the B9143 extending to meet the A905 and M9 at the Cadgers Brae Roundabout. The later, and current line of the A905 to the east, which stole the southern end of the B9143, seems to be part built on these maps, but the Avon Bridge is not shown.
