A new set of 2 packages
1. Highway dual lights
2. Cement road barrier
the lights are found under Lighting/Outdoor Lighting, the cement barrier found under Decor/Misc. Decor, they all cost 0.
Use the Property Browser in CAW to set the lights and the cement barriers, all at the same height and all lined up. I used 2 cement barriers between every light and a gave it a little gap on both sides of the lights to the cement barriers. I've used the lights and cement barriers on the flyover and the lights only on the ultra modern suspension bridge. You need Late Night or a later expansion pack for the lights to show in your game.
