1:00, 47 km to border of West Kalimantan and Central Kalimantan, but we detoured through village of Tanjung Assam to meet friends.
Then 8:30, 399 km to Sampit
Almost immediately after the border, the dreadful bridges are obvious. I saw two that had a truck upside down in the river below. They are not motorcycle friendly, especially the transition onto the bridge.
However, every one of them had a work crew building a nee bridge. So in six months this will be a much easier ride.
The route is not very easy to follow, with many intersections lacking signs. There are many deep holes and unexpected dirt latches in otherwise good roads, so ride with caution.
