Beginning Saturday afternoon, State Route 77, known locally as Navajo Boulevard, will close in both directions for about four days at the Burlington Northern Santa Fe Railroad crossing in Holbrook so the railroad company can replace the crossing.

The highway closure, expected to start at 1 p.m. and last through Tuesday, Oct. 25, will impact drivers in the Holbrook and White Mountains areas.

Highway detours for commercial vehicles and non-local traffic around the closure include:

• US 180 to US 191 at Sanders to access I-40. Drivers on the north side of the crossing can take I-40 to Sanders then US 191 south to US 180 to SR 77.
• Drivers can also take I-40 west to SR 87 in Winslow and head south to SR 260 to get to Payson. Traveling to SR 277 will take drivers to the Heber-Overgaard and Snowflake areas.
• Those in Show Low looking to access I-40 can take US 60 to SR 61 to St. Johns and head north on US 191 to Sanders to access I-40.

Provisions will be made for emergency vehicles to get through the closure if they are on an emergency call.

There is no parking allowed in the vicinity of the construction site.

The railroad crossing is beyond its service life, requiring Burlington Northern Santa Fe to replace it.
