I-405/NE 8th St to SR 520 Braided Ramps - Interchange Improvements
It is highly congested in the vicinity of downtown Bellevue and the I-405/SR 520 Interchange. On and off ramps will be constructed. Relieves congestion on northbound I-405 caused by the weave between the on ramp from NE 8th and the off ramp to SR 520. Relieves congestion in the vicinity of the I-405/SR 520 Interchange caused by the weave between the eastbound SR 520 off ramp to 124th Ave and the on ramp from northbound I-405 to eastbound SR 520. Improves vertical clearance at the NE 12th Street crossing. The reduced congestion will result in a decrease in the number of accidents.
