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. <br>
<br>
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.<br>
<br>
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Libby Road will be superseded by Davao Bypass Road.<br>
<br>
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.<br>
<br>
Best regards,<br>
Timmy<br>

<div dir="auto">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.</div>

<div dir="auto">- 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).</div>
<div dir="auto">- 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).</div>

<div dir="auto">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. </div>
