Junctions 7 and 8 were also remodelled into a roundabout junction. The Avonmouth Bridge was converted to eight lanes four lanes in each direction in the early s. Later, in —, parts of the M5 between Junctions 17 and 20 were widened to seven lanes four lanes climbing the hills and three lanes descending the hills ; variable message signs were added and parts of the central reservation was converted to a concrete step barrier. During this stage of construction the M5 became Britain's longest contraflow system, [7] [8] spanning 9 miles between Junctions 19 and The M5 contraflow was said to be the most complicated ever built in the UK as the motorway is on a split level around the steep hills of the Gordano Valley ; meaning four lanes plus an additional emergency vehicle lane were squeezed into that section.
In extended exits for Junction 12 were constructed. The Highways Agency did not anticipate the traffic flows through the junction and the resultant queues can now extend back onto the motorway, [10] because of an increase in traffic from Stroud intending to use the M5 northbound.
The distance from Junctions 12 and 13 is similar and traffic congestion is heavy on the A towards Junction 13 whereas it is usually lighter on the B towards Junction As traffic leaving the M5 northbound towards Gloucester needs to give way to this traffic coming from the B, the queue on the motorway can extend beyond the first sign for the junction.

Dudley , Wolverhampton , Birmingham West A Birmingham South A38 Stourbridge A Droitwich , Bromsgrove A This resulted in several years of delays while the bridge was also strengthened. The section between junction 19 Gordano and junction 20 Clivedon is probably the most spectacular section of the M5.
The carriageways are terraced into the side of a rock face, the southbound being at the higher level. The M5 continues to wind its way through Somerset and north Devon wind being the operative word since there seems to be an awful lot of bends on this section. Scenery is rural and not particularly spectacular. At junction 30 Exeter traffic from the east A30 joins the motorway which can cause congestion, particularly during the holiday season.
The M5 ends at junction 31 south of Exeter flowing directly into the A38 what else! This road continues for a short distance as dual 3 lanes before brabnching into twin dual carriageway routes for Torbay and Plymouth respectively. Try getting involved! Does this contradict the conclusion we reachedhere this thread or is the map wrong? No sign of the Exeter bypass, nor of the Taunton to Bridgewater section. The section north of Bridgewater is shown as complete on one page opened and under construction netween Burnham and Bridgewater on another page.
This would suggest that the atlas is a little unreliable in terms of dates. It shows the motorway as complete between M6 and Burnham, including the Avon bridge, but this contradicts earlier posts on this thread. Again, I am inclined to believe Ian rather than the atlas as it tends to show roads open that are due to be opened in that year. Can anyone confirm why the Avon bridge was delayed. I have an idea that it is a steel box girder bridge, and that all this type ofstructure were delayed following the collapse of the Cleddau bridge near Pembroke whilst under construction.
Other roads delayed as a result of this included the M6 Midlands link to the north of Birmingham. Is this correct? The Avonmouth bridge was indeed delayed for several years due to the bridge collapse. The motorway was opened at junction 19 Gordano but this was a very quiet section as it was just as quick to rejoin at junction 21 Weston.
However I always tried to persuade my parents to take the detour back to junction 19 as I was always fasinated by the 'terraced' section between 19 and Actual opening dates of other sections are rather hazy in my memory but some certainly opened out of order. For instance the motorway was opened to 24 and then 25 - 26, leaving a missing link.
This resulted in horrendous queues during the holiday season as traffic stacked up leaving the motorway at 24 and again at It might have been better to open it all at the same time. For all today's congestion problems the journey to Cornwall is certainly easier now than in the 's - I speak from experience. A30 Bodmin - Indian Queens remains as a major bottleneck however. Regarding other bridges being affected by the safety scare I believe the 'Midland Links' viaducts were opened in and were unaffected by the safety issues.
Do you know anything more of the the Cleddau collapse? Can anyone confirm? The old Cullompton bypass ran between the current B overbridges either side of the town at Willand and Westcott. The old A38 through Cully was, for a time, part of the B I don't know whether the bypass was built in its current form 3 lanes plus hard shoulder - I'm only as old as the motorway itself! What I can say is that the overbridge and junction layout at junction 28 appear to be of an older style that the surrounding sections of motorway - I would guess mid 's.
