wegenwiki has even less routes. However, I've checked the references list of the wikipedia article and there's a "
list of roads maintained by the highways division" (Port of Spain, Trinidad and Tobago: Ministry of Works and Infrastructure (Trinidad and Tobago). Retrieved 2021-12-30.) I don't know it it's really from the end of last year (no date in the document) but if so, it might be interesting.... Issue no.1: The table has a column "Route No" (which are not signed, are they?) in addition to "RoadName"
"Functional Class" indicates if the route is "Main", "Highway", "Secondary" and "Tertiary"
The document is quite long, it has 21 pages
@si404 Should we use this document as source?
