Two accidents on Interstate 395 North are causing significant delays this morning. 

The first crash early Wednesday morning blocked the right and center lanes of I-395N near Duke Street. 

Another accident near Edsall Road shortly before 7 a.m. is also blocking the right and center lanes. 

The incidents have caused several miles of backups on northbound 395 and are contributing to delays heading towards the Beltway, officials said. 

No details were immediately available about the severity of the crashes. No injuries have been reported.
