The main road east, now largely unrecognisable for the way it has grown, with the urban sprawl making it difficult to spot the boundary between Fareham and Portchester. It was designated A27 in 1922 and still holds that status today, even if it was detrunked in 1977.
Starting at Delme Arms Corner, which takes its name from the pub at the junction, which itself is named after Peter Delmé, who between him and his family owned Cams Hall for nearly a century in the 1800s. Once a crossroads, where Cams Hill flowed on to East Street, crossing Wallington Shore Road and the wide entrance to Cams Hall, the area is now overshadowed by the modern A27, with only the suspect kerblines and the isolated section of Wallington Shore Road providing evidence of the junction. Cams Hall is thought to be a 13th Century manor house that has been extensively modernised, but was passed between owners in the 20th Century, and in 1953 an explosion at the naval storage yard left it heavily damaged and it fell in to disrepair. The death of the next leaseholders, the Hill family who had intended to make it a caravan park, as well as further vandalism saw it listed as derelict in 1989, but a restoration programme beginning in 1991 saw it refurbished to become a business park. It is from here that the name Cams Hill, used by the road past the site and the adjacent school, was taken.
In the mid-1960s a small portion of North Park, where the Hall is built, was sacrificed for the construction of the new A27 Cams Hill, taking it away from the narrower, uphill climb and the 19th Century cottages. It had been used to host funfairs. The offline improvement in theory allowed a lot of woodland to be saved, although how much was isn't clear, it probably later fell naturally. Many of the trees here had been planted as part of a project in 1927 to spruce up the area. There is some confusion over which road is what: it appears that the old road was originally Portchester Road, and then the name Cams Hill stuck. The new road is also known as Cams Hill but only between the lights - the rest of it is referred to as Portchester Road.
Downend Dell, a singular property located in a valley, became multiple houses known as The Dell in the 1980s.
Here a gap is provided for the old road to meet to the new one. The wonderfully named Paradise Lane is a historic lane running up to Military Road, once serving Downend Farm, which was on the eastern side right up against the railway line, although now it is more of a public footpath. At the bottom, the Downend Cottages. Further up, the road has been consumed by the developments along The Ridgeway and The Causeway in the 1960s (the area around the farm was last to turn residential).
At St Catherine's Way, the new road bears north, crossing the path of the old one. St Catherine's Way was originally the entrance to Downend House, owned by Charles Osborn. In the 1940s, this land was broken up for development. The house was later demolished to form Alum Way, and over time, some of the large plots of land which these houses hold have been broken up for more housing.
In 1958, Fareham Girls' Grammar School (becoming Cams Hill mixed school in 1975) was built on the land known as North Park, accessed from a long driveway off of Birdwood Grove. In the 1990s some of their land was sold off to create Shearwater Avenue. East Cams Close takes up the land formerly occupied by East Cams House, which formed part of the East Cams Farm. There would have been a tollgate somewhere around here. Opposite, a row of 1940s houses is set back from the road. Despite it aligning perfectly with other sections of old road, it looks like this one was misleadingly added. In addition to Birdwood Grove, a long, straight, suburban street, was built. Another field was sold to create Cams Bay Close in the 1960s.
The Thicket and The Spinney were originally built to house prisoners of war (camp E251), many of whom later became integrated in to the local community, with today's housing being developed after 1965.
Moving along the road, the earliest houses on the road itself arrived at the start of the 20th Century. In the 1980s, Condor Avenue was built, with the associated roundabout. It wasn't until 2005 that five old houses on large plots of land were demolished to make way for Oysell Gardens.
Cams Bridge (accessed from The Thicket) leads to Winnham Farm, although it must carry some significance if it is named as such. The road through here is wide, but appears to have formed with little encroaching on to private land. 8 houses east of Beaulieu Avenue was the West End Farm, the land from which allowed the road to be upgraded to a dual carriageway, with the eastbound side being the old road. This was one of the proposed crossings of the M27 in the 1950s.
From here on, as we head in to Portchester, things become more vague. The streets which we pass are:
- Winham Drive - 1970s
- Rockingham Drive - 1990s
- Romsey Avenue - 1960s
- Cornaway Lane - 1920s/1960s
- The BP garage was originally Huxfords
- West Street finished in the 1970s
- New Town - 1930s
- Castle Street - various, mostly 1920s
- St. Helena Way - 1960s
- The remaining residential streets were mostly 1950s
The road was once known as Fareham Road, but this name appears to have been lost as the Fareham boundary became less pronounced. It passed through a crossroads, with a stub in the middle of the roundabout being a remnant of this. The smaller, parallel West Street isn't actually the original: it was built with this area in the 1950s as part of the post-war development of the south. This moves in to Portchester village, where the West Street bypass was built in the early 1970s to relieve the streets. Previously, the old road was Main Road, but it was renamed during early 20th Century redevelopment. The original line, crossing Castle Street was a poorly reputed crossroads, which can still partially be seen in the alignment of the pavement, past Portchester Farm, where it went on to become East Street and later Cosham Road (now Southampton Road).
