[talk-ph] Your final say on the proposed road classification scheme

[Timeo Gut]

I'd like to discuss a possible downgrade of primaries in Davao and CDO. 
I think several of these roads are good examples for unnumbered routes 
with major importance.

Let's start with Davao. Since the opening of Slaughterhouse Road and the 
subsequent widening of Gold-Ruby-Mabini to 4 lanes most through-traffic 
from Diversion Road to downtown (previously passing through Ma-a) is now 
being diverted through this more direct route. Given that Ma-a now 
mostly serves local traffic (the main exception being connectivity from 
Calinan-Magtuod Road to Matina), downgrading to secondary seems 
appropriate. It should be noted that the current main link between 
Diversion Road and Downtown is only intended as a temporary solution 
which will become redundant with the construction of Davao City 
Expressway Phase 1. This planned project would also significantly reduce 
the importance of Bacaca Road, which could then be considered for 
downgrade to secondary.

Some background about Libby Road: Under the project title Davao City 
Diversion Extension to Toril this road has been fully widened to 4 
lanes. Together with Talomo-Puan Bypass it serves as a feasible 
alternative route from Bangkal to Toril. Especially for traffic to and 
from N10 it's almost always the faster route as it bypasses Crossing 
Ulas and Crossing Puan. It should also be considered that Toril is a 
town-like suburb that far exceeds the population criteria laid out for 
primary roads. I think it would be best to keep the current 
classification for now and only downgrade to secondary once Libby Road 
will be superseded by Davao Bypass Road.

As for Manolo Fortich-Libona-Indahag Road, in its current state it is 
clearly sub-standard for a primary road, especially the section from 
Indahag to J.R. Borja. Despite of that it serves as a viable and in some 
cases faster alternative for travel between two large population centers 
within Metro CDO. Maybe we can ask for opinions on this from local 
contributors. Edge cases like this are really difficult to assess 
without extensive ground knowledge.

  Best regards,
Timmy
