Located 2 miles (3.2 kms) east of La Mure in France’s beautiful Rhône-Alpes region is the Roizonne arch bridge. Originally a railway bridge, the span was eventually converted to road use. Also referred to as the Pont de la Mure, the main arch of 244 feet (74.44 mtrs) is a semicircle with 4 smaller arches above the spandrels on either side.

The La Mure region has 4 other high bridges worth visiting. Just 1 mile (1.6 kms) south of town is the famous Ponsonnas arch bridge over the Le Drac River. Originally built in 1863 as a suspension bridge, it was replaced with a concrete arch in 1941 that was designed by the famous French engineer Albert Caquot. The original suspension bridge towers assisted in the construction of the new arch. Ponsonnas is a popular bungee site. You can find out more here:

5 miles (8 kms) further west, a suspension bridge along route D34 crosses at least 164 feet (50 mtrs) over the L'Ebron arm of the Lac Monteynard-Avignonet reservoir. Just downstream of the D34 crossing is the Passerelle L'Ebron, one of two high footbridges that cross over the Lac Monteynard-Avignonet reservoir. The other is the Passerelle Himalayenne over the Drac and located 4 miles (6 kms) southwest of La Mure at the small town of Mayres-Savel. Both are at least 164 feet (50 mtrs) above the water - even higher if the reservoir level is down.
