SANTO DOMINGO. – Hundreds of motorists who headed from Santo Domingo to Samaná yesterday were turned back by the tolls’ guards, who said the Yabacao river washed out a section of the new highway, at Monte Plata province, after Tropical Storm Fay dumped heavy rains in that part of the country.
The military allowed traffic only as far as the village Naranjo, as flooding in the zone affected about 16 kilometers of the road. Only moto-taxis were allowed on the highway and some vehicles were seen returning from Samaná to Santo Domingo.
Meanwhile traffic is snarled in Sabana de la Mar as recent rains caused landslides and crevices along a 200 meter section of the highway linking it with Hato Mayor province, whose governor Jose Alberto Vásquez called on Public Works to restore transit between El Valle, Miches and Sabana de la Mar.
The Sabana de la Mar-Hato Mayor highway was under reconstruction, but the work was abandoned soon after president Leonel Fernandez won reelection.

No engineering structure is ever designed to withstand hazards of BIBLICAL PROPORTIONS. It would cost too much. With your expertise in hydraulic structures, geology, hydrology and earth movements, I am sure you could deduce exactly how it all happened. The USGS awaits your report. Jawohl Herr Doktor Johann?
a concession to some foreign company,, i say shoddy workmanship, but somehow the concessionaire will get the gov't to pay for it...god more BS!!!!
In short, here highway construction is not a science.
For example, the puerto plata-santiago touristic highway has has dozens of landslides (derrumbas) and almost all are the result of drainage canals being covered or blocked and runoff from heavy rains over-running the highway.
drive 60 kmph and be carelfull...
Everything in the DR has corruption and incompetence built in.
Mother nature just showed them how big a water shed they should have built.
And NO do not steal the concrete that should have gone there. It's like dealing with 10 year olds.
