Yes, it's a usual routine. Streets closed without barriers or signs. Huge drop offs between existing pavement and new construction again without signs or notice. Fremont is inaccessable to Benito Juarez, at this moment in time due to a huge drop off. The detour from BJ to Fremont is around the park but is unmarked. Access to the Malecon is via Calle 8 in the Mirador to Benito Juarez. Luis Encinas is blocked off as are all the streets around the harbor for access to the Malecon at this moment. This could change as the blockage is for demolition and they did reopen BJ between demolition and resurfacing.
Locals know how to get around but the visitors do not. Have had a couple looking for access to the Malecon come in asking how find it.
