I recently created a proposal for the types of road construction. The key should be used with highway=construction to specify the type of construction being completed. The new key is named construction_type and has 4 possible values:
build: A new road being built.
pave: An existing road being paved or repaved.
reconstruct: An existing road being reconstructed.
I think it would be interesting to see some concrete use-cases for this. One use-case I quickly thought of was to approximate for how long the construction will be ongoing (building takes longer than paving etc.), but we already have tags for that (opening_date).
Regarding the proposed construction_type=pave especially; most re-paving jobs (at least here, in Sweden) are over within a timeframe of weeks to at worst months, which is commonly regarded as too short/temporary to be mapped in OSM.
If this key would be accepted; I also think it’d make sense to add a value to represent infrastructure work (when the road is torn up to work on underground infrastructure such as pipes).
@02JanDal I’ll remove paving, and infrastructure work is infrastructure, will add @VShkaberda In the above entry it states that I will remove paving according to @02JanDal’s suggestion. @Mateusz_Konieczny It is used to map what specific construction work is taking place on a highway/road.
