I had a brief look at your MyMaps. I believe all the Klang Valley Expressways you have there are already mapped (and at higher details) in OSM. Did I miss anything?
(1) PLUS (ELITE, NKVE)
(2) Litrak (LDP, SPRINT)
(3) Gamuda & Co (KESAS, SMART)
(4) IJM Corp (NPE, BESRAYA, LEKAS)
(5) Tailworks Corp and EPF (Grand [Saga, Sepadu])
(6) Prolintas (SILK, GUTHRIE, AKLEH, SUKE, DASH)
(7) Maju Group (MEX)
(8) Bina Puri (LATAR)
(9) Ekovest (DUKE [1,2, SPE])
(10) Other Owners (LKSA, SKVE, EKVE)
Is there really any of above highways missing from OSM? OSM includes highways completed as well as those under construction.
