Attention, Baltimore commuters: The JFX has been reduced to two lanes in each direction. That means, come Monday morning, it's going to be extra-crowded on the expressway. To get to work on time, check out the directions below for alternate routes into the city. And leave early!

The expressway's left lanes have been closed near 29th St. and Druid Lake Drive to permit repairs to damaged drainage pipes under the highway, said the Baltimore Department of Transportation, which expects the project to take as many as eight weeks.

The department urges commuters to not rely on the JFX.

"The remaining two lanes in each direction will not provide sufficient capacity to accommodate traffic demand and, accordingly, severe congestion will result unless there is a significant traffic diversion," the department said in a statement.

Translation: You'll regret it if you get on the expressway during rush hour.

The transportation department asks commuters to consider public transportation: local or express buses, the light rail and the Metro.

If you must drive, the department has provided turn-by-turn directions for nine alternate routes into the city from the northwest, north and northeast.
