The long-term construction on northbound Interstate 95 in Baltimore will once again shift lane patterns this weekend, forcing ramp and exit closures in the process, according to the Maryland Transportation Administration.
The current split between Caton Avenue and the Fort McHenry Tunnel of two lanes on the left and two on the right will change to three lanes on the left and one on the right sometime after 9 a.m. Sunday.
Traffic in the right lane will be able to exit onto Russell Street, Interstate 395 and Key Highway.
Traffic in the left three lanes will not be able to exit onto Russell Street, but will be able to exit onto I-395 and Key Highway. Drivers in the three left lanes who intend to exit onto I-395 or Key Highway should stay to the right.
Traffic that does not exit at I-395 or Key Highway will have to continue on to the tunnel.
No northbound I-95 traffic will be able to exit onto Hanover Street. Traffic bound for Hanover Street will be detoured, via Key Highway and McComas Street.
In addition, starting after 9 p.m. on Friday, the exit from Route 295 onto northbound I-95 will be closed.
Traffic bound for northbound I-95 from Route 295 will be detoured via the service loop that drivers on Russell Street can merge onto on the right, just north of M&T Bank Stadium, to loop south again to southbound I-395.
All of the changes will remain in effect until mid-September.
The work is part of a two-year, $66 million project to replace concrete deck surface and joints on I-95 and the ramps serving it.
