JERSEY CITY — Route 78 will have two trouble spots for drivers all weekend long.

The highway, which becomes the Newark Bay-Hudson County Extension of the New Jersey Turnpike, will be reduced to just one lane westbound between exits 14A and 14 across the bridge, and eastbound between Exit 14C and Jersey Avenue until 5 a.m. on Monday.

The closures are expected to create long delays for those headed west to the Turnpike and east to the Holland Tunnel.

Weather permitting, crews will be working on "high-priority bridge deck repairs and resurfacing," according to the Turnpike Authority.

Bridge deck work will also close the ramps from Route 78 in both directions to Routes 1&9 south until 5 a.m. Monday. The DOT said the decks would be removed and replaced along with retaining walls.

The $26.6 million federally funded project to replace three Route 78 bridge decks began in February and should be complete by the end of 2018, according to the DOT.
