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will be superseded by Davao Bypass Road.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

On the proposed reclassifications I'm documenting at uMap, I've been
trying to identify trunk and primary routes across sprawling urban
areas of places like Metro Manila, Metro Cebu, Davao and Cagayan de
Oro. Those places are are a different beast from the rest of the
country. What route gets trunk Class needs to be carefully selected
especially where they’re part of the same corridor. Primary should
generally be assigned to main thoroughfares, and for me, best not
assigned on any road without a road number, with the possible exceptions.
Some ideas:
- For Davao City, trunk network is fine. Primaries around Davao City
may need some partial tweaks, especially those linking C.P.
Garcia/Diversion Road with city proper. Should consider downgrade for
Libby Road between Toril and Talomo (would consider this secondary
being functionally lower than MacArthur Highway, plus road being
narrow and classified national tertiary).
- For Cagayan de Oro, trunk network is fine (may move trunk
classification to the bypass formed by the Coastal Roads, San Pedro
Street and San Lazaro Road once the missing link near port opens).
Primary network good, but should consider downgrade to J.R. Borja and
the road to Libona and Manolo Fortich (low speeds, narrow carriageway,
less traffic and lower official classification).
Sorry for the late reply, having another pause from mapping. I've been
also looking up the talk-us archive for the latest discussion on
reforming U.S. road classifications that has been pointed out earlier
here.
