![]() ![]() The 2 lanes of the Bradfield Highway that follow Cahill in parallel continue uninterrupted to existing 4-lane highway of the Trans-Manukau Link. The 2-lane Cahill Expresway effectively services as a mega long off ramp from the Manurewa/Papatoetoe side of the river to the Manukau River Town Roundabout. Given the Trans Manukau Link is an existing highway the layout of the Sydney Harbour Bridge in my example fits perfectly well. A 6 lane two way motorway (4+2 but I believe this can tidal in real life) or the Bradfield Highway and the 2 lane one way (including a single bus lane) Cahill Expressway make up the roadways while either side is flanked with shared paths and finally heavy rail to take passenger trains on one side. As with the real-life Sydney Harbour Bridge the asset has two actual motorways on it rather than one.
