Altough I'm late giving out this news (from september 18), this highway finally opens to traffic, after 30 years of construction.
This new toll highway mostly its 4 lanes, it has 6 tunnels and one of the talles bridges in Americas, San Marcos bridge...
QuoteThe President of the Republic, Enrique Peña Nieto, has officially opened the new Nuevo Necaxa-Tihuatlán motorway, constructed by FCC Construcción and ICA. It is one of the biggest infrastructure works of the current President's term of office. The motorway crosses the states of Puebla and Veracruz, forming part of the Mexico-Tuxpan corridor, the main highway axis joining the Federal District to the Gulf of Mexico.

I looked it up on Google Maps. I'm guessing it is Highway 132D. Thirty years is a long time, but at least they didn't abandon the project all together. EDIT: I'm kind of surprised they didn't make the San Marcos bridge a suspension bridge.
The San Marcos Bridge has a significant incline, Google Earth altitude measuring suggests it loses about 50 m / 165 ft in altitude over the 840 m / 2756 ft length, which would be around 6%. It is unusual for suspension bridges to have an incline.

There are a couple of old Ohio River bridges that incline from one side to the other due to the bluffs. Offhand, don't recall which, or whether they were suspension or truss. But yes, it's unusual for a bridge to be asymmetrical.
