We’re asking residents for their views on proposed improvements to major junctions on Plymouth’s Major Road Network (MRN).
The plans are focused around three key sections along the route – Marsh Mills Roundabout, Embankment Road and the St Budeaux Bypass – and includes lane widening, junction capacity upgrades and new facilities for pedestrians and cyclists.
To help break down each aspect of the scheme, here is the latest in a series of features about the different aspects of the plans, this time focussing on Marsh Mills.
Have a ready through and then head to www.plymouth.gov.uk/MRN to give us your thoughts.

Marsh Mills has long been one of Plymouth’s busiest and most important gateways, funnelling traffic from the east into the city and connecting drivers to the A38, Plympton, Leigham and the wider road network.
As traffic levels have grown, so has the pressure on this major junction and a series of proposed changes aim to make it work more smoothly for everyone who uses it.
The plan focuses on Marsh Mills roundabout itself along with the roads feeding into it and includes widening several approaches to increase capacity and ease queuing at peak times.
One of the key changes would extend the second lane on the Embankment Road northbound approach for drivers heading towards the A38 Liskeard and Leigham Roundabout.
This extra space should help reduce the stop start conditions that often build up here and allow more vehicles to merge without slowing the entire approach.
On the opposite side, a new additional lane is proposed on the Leigham Roundabout approach for traffic heading towards Exeter. This creates more room to separate out different turning movements, making it easier for drivers to get into the correct lane earlier, helping the whole junction run more efficiently.
There is also a specific improvement planned for drivers heading into Sainsbury’s, where an extra lane would separate traffic heading for the petrol station from those going to the main store. Anyone who regularly uses this entrance knows how quickly queues can build, so this change should make a noticeable difference during busy shopping periods.
On the roundabout itself, an additional lane would be added between the Plymouth Road/Embankment Road northbound entry and exit arms. This would create two clear lanes for vehicles heading towards Leigham Roundabout or the Cornwall-bound A38 and two lanes for those travelling towards Plympton.
Public transport is also set to benefit. A new bus lane on the northbound approach along Embankment Road and Plymouth Road will allow Plympton bound buses to move ahead of queuing traffic when the roads are busiest.
This should help keep services running on time and reduce the uncertainty that drivers and passengers often face when buses get caught behind long lines of cars on the approach to the roundabout.
People walking, wheeling and cycling would see significant upgrades too. The uncontrolled crossing over the vehicle entrance into Sainsbury’s would be replaced with a safer and more predictable signal-controlled crossing with the path either side of the crossing widened.
This connects neatly with the paths that run between Plympton and the city centre, strengthening an already well used active travel corridor.
Another major improvement focuses on the narrow crossing under the Marsh Mills flyover near the Beefeater. At the moment, cyclists must dismount and the middle section is extremely tight due to the flyover wall.
There are two options up for consultation. The first proposal widens the existing shared path either side of the crossing by shifting the road slightly and creating a new segregated path that continues under the flyover.
The second proposal replaces this crossing with one nearer the junction, where the traffic island that separates Plympton and Leigham traffic would be widened to accommodate a two-stage crossing point.
A further improvement realigns part of the off-road walking and cycling path on the eastbound approach to create a more direct route away from the busiest parts of the junction. This aligns better with where people naturally walk and cycle through the Retail Park and improves the overall experience.
Together, these changes aim to make Marsh Mills easier to navigate, safer to cross and more reliable for everyone who depends on it, creating a smoother gateway into Plymouth’s eastern side.

Leave Marsh mills as it is, you will just cause more problems with your poor planning as usual
More traffic misery for years while it is done with the prime SIM of spending more on cycle lanes for the twelve cyclists in the city
