If there is really a legitimate need for such a road, then measures should be taken to make sure the road is used only for transportation among the various towns. It should not become a magnet for real-estate developments, which would devastate some of the most beautiful and remote areas of Lebanon. The good news is that Wadi Jhannam and Horsh Ehden have been designated as protected areas. Unfortunately, one road several kilometers long was built through a forested area in the foothills of the east side of Mount Lebanon, from Nabha to the existing road north of 'Ainata. It is not far from from an existing road from Nabha to 'Ainata, and probably saves no more than a few minutes of travel time.
Farther south is an another disturbing road.
My last trip to Faraya was in 1983. The road there always passed through Faitroun, Mairouba, Hrajel, and Faraya-Village. I was shocked to see that a new road had been built, bypassing those towns and ruining a rare unspoiled gorge in a Keserwan already devastated by a dense spaghetti of roads and runaway development. This road takes off from the bottom of the Nahr el-Mghara gorge between Faitroun and Mazra'at Kfar Debian, an area of steep cliffs and sculpted karst rock formations. The map's color legend shows it as now being the main road to Faraya.
