Pont Julien
Our fourth day started with a visit to the Roman bridge Pont Julien. You can tell that water levels have changed during the last two thousand years. The bridge has high archways, in anticipation of high water levels -- levels that would approach the top of the arch. On either side of the arch are openings. These were designed to allow water to pass through the bridge during periods of high water, otherwise the bridge could have been washed away.
Seeing the bridge in person is impressive. But after taking the picture above, we then drove over the bridge in the Weyfarers car. Despite being 2,000 years old, this bridge is still used as a major road today.
