Pretty bad at the game and this is my only city that doesn't just connect a highway to a roundabout. So im wondering how i go about building on the huge area to the right, theres 20k people living on the left and im planning to build it as a grid but am wondering if i should just create a new highway to cover more of the island to the right or just build six lane roads across the grid as shown in the picture. Also any tips on what i could improve in terms of road layout would be appreciated.
