If they can only afford one set of traffic lights then they should have put them in a location that is very dangerous at some times of the day and that is where the diversion road crosses Jose Romero road.
A lot of people are very impatient crossing here and as there is not even a sign to show which road has right of way it's complete chaos.

 

There are traffic lights installed (not functional yet) where the diversion road meets the national highway at the Bacong Dauin boundary. My neighbors have started a pool guessing when an overloaded sugarcane truck will take the lights down.
DPWH installed some small concrete islands to encourage drivers to enter and exit the diversion road from the proper lanes. So far this has not gone well as trucks coming from Dauin need to be in the right lane on the national highway to turn left onto the diversion road. Large trucks have great difficulty making that left turn. I sat one day watching for 5 minutes as a truck tried to negotiate the turn.
Once the lights are operational it'll be time to start the party. LOL
