The SCTEx Exit is a few meters after the Dau Exit of the NLEX. There is a short spur road which will take you to the actual SCTEx. What I found amusing is the fact that there were several signs which had the wrong spelling of MacArthur Highway. To the silly person who did those signs, it's "MacArthur" not "McArthur" since the road is named after Douglas MacArthur! That's what we get for having too much of McDonald's.
On the way to Subic from Clark, the only open exits in the SCTEx are the ones in Dinalupihan and Subic. The SCTEx ends right at the entrance of the Subic-Tipo Tollway so it's really convenient for those going to Subic.
We tried it out on the way to Subic today and it was worth the trip. Imagine arriving in Subic from Clark in just 35 minutes! I still remember the days having to pass through all the traffic in Sta. Cruz, Lubao, Pampanga and other busy intersections along the Gapan-Olongapo Road (now Jose Abad Santos Highway). Finally, smooth travel all the way!
I hope they finish C6 - Lakeshore Expressway soon. The proposed expressway will connect Cavite City to Marilao, Bulacan as well as the SLEX to the NLEX so that you need not travel through chaotic Metro Manila.
Add to that the fact that the highway is so scenic. It passes through the untouched countryside in Porac and Floridablanca, Pampanga. The drive itself is an attraction you should not miss! Enjoy it while it lasts because I could already foresee development creeping in as the different exits are constructed and opened.
And if you make it just in time for sunset (we were almost not allowed inside since we were a few minutes late) the views are nothing but surreal.
