Suggested Solution

Walmer Blvd / M4 Tee Junction

Port Elizabeth


In this proposal the traffic signals are decommissioned and the T junction assumes the shape of a flattened traffic circle, about 500 meters long. On the northern side a half circle is created through a vacant parking area below the elevated M4. On the southern side a half circle is built on vacant land adjoining the narrow gauge railway terminus. Traffic lanes are rearranged to create a continuous flow pattern and waiting at traffic signals is eliminated

Pictorial Sequence

   1

Summerstrand traffic turns left
traffic signal is decommissioned

   2
Summerstrand traffic turns right
to underpass below elevated M4
   3
South bound Summerstrand traffic goes under elevated M4
   4
Walmer Blv to Summersrand exits from under M4 Bridge
   5
Summerstrand traffic prepares to merge with
traffic from CBD
   6
South bound lanes are re-aligned to run parallel with
and merge with M4 lanes
   7
South bound traffic lanes merge with M4 and crosses existing "jug handle"
lanes. No right turns to Walmer occur at this point
   8
South bound lanes diverge to the left from existing Humewood Road
and rounds a new half circle to be built on vacant ground adjacent to
narrow gage railway lines. At this half circle Summerstrand bound
will go straightand Walmer traffic will double back a about 250m
to make a left turn onto Walmer Boulevard
