National Secondary Route 257 is an arterial road from Route 32 to the Moín Container Terminal in the Caribbean sea of Costa Rica.
This is a 2.3 km two lane road, one in each direction, that was created for the cargo transportation between Route 32 and Moín Container Terminal.[1]
At the time of its construction, it was heavily criticized due to a critical geographic gaffe, as there was a problem of communication between the actors involved, with an 80m error in the design plans, and a whole new redesign was required for a much more expensive road than projected, at about an additional CRC ₡7,900 million,[2] including an elevated highway with a length of 817m.[3]
The country comptroller was involved in the investigation of the gaffe.[4]
The road was opened for general use on 26 January 2018, it took eighteen months to complete.[5] [6]
