Level 2 Unlock Help

Hi Guys

Ive been editting quite a bit in mombasa and around… But I’m a little stuck at the Nyali Bridge Area (Ronald Ngala Road) The roads are dual carriageway, and i have done a couple, but the problem is it needs changing on the bridge too. Im a level one, and the section on the bridge is a level 2. Any Help would be much appreciated. 4.0439 S 39.66647 E
