B790 Bridge of Weir - Inchinnan

The B790 is a short B-road in central Renfrewshire, which runs from the centre of Bridge of Weir to Barnsford Toll Junction on the A726 at Inchinnan Business Park, near Glasgow Airport.

Route

Bridge of Weir

The B790 heading out of Bridge of Weir

The route starts at traffic lights on the A761 (former B788) near the centre of Bridge of Weir and heads east through a council housing estate.

A few private houses and a fairly large park on the left mark the edge of the village.Opposite the park, Houstonhead Dam can be seen across a field on the right as we enter a short stretch of countryside between Bridge of Weir and Houston.

Houston

The B790 Houston bypass. The hatched area in the distance is where the B789 joins from the left

Approaching Houston, originally the road went 'straight on' and through the village but now sweeps right and then left to bypass it to the south, running more or less parallel with the old alignment for the first 800 metres or so.

Gryffe High School stands in the space between the old and new alignments, shortly after which the B789 comes in from the left and multiplexes along the B790 for 400 metres to a roundabout where the B790 continues past - but not through - the houses to reach the far end of the bypass, where the old alignment joins again on the left at the outskirts of the village.

Flat country to Inchinnan

Long, flat straights are typical of this stretch of the road

The road continues east, mostly straight across low-lying and mostly flat land, but a short rise with a blind summit at Loanhead and a pair of bends shortly afterwards have double white lines.

The crop here is traditionally rhubarb and giant stalks of it can be seen in the fields when it is in season in late spring and early summer.

Opposite the rhubarb fields, the remains of ROF Bishopton (munitions and propellant factories) are gradually being cleared and replaced by housing, although not much can be seen from here due to the high fence and screen woodland. The site stretches for almost three miles. Part of the site is still owned by BAE Systems, who have facilities there, hence the high fence around it. Just after the C4 joins on the right, a gated entrance to BAE is located on the left, where a third lane has been added the B790 to assist right turns.

The bridge under the M8, with the railway bridge just visible underneath

The road then runs parallel to the River Gryfe for a short distance before going under the Inverclyde Line railway at the site of the former Houston and (earlier) Georgetown stations. A second bridge in quick succession passes under the M8.

After passing under the bridges, the road continues dead-straight for another few hundred yards before passing a Territorial Army depot on the right and a former NATS building on the left.

The route ends at Barnsford Toll, which is a T-junction on the A726 at the edge of Inchinnan Business Park near Glasgow Airport.

History

Pre-1960s OS maps show that the original road continued straight through Barnsford Toll Junction (the area now occupied by Inchinnan Business Park) and ran to the India of Inchinnan tyre factory, where it ultimately reached the A8.
