The Chicago Transit Authority stages a double-header in Evanston this weekend — rolling in two new Purple Line viaducts — at Dempster and Grove streets.
The performance follows the successful roll-in of the Greenleaf Street viaduct two weeks ago.
'The project will require shutting down Purple Line service from Howard to Davis from 8:30 p.m. today through 4:30 a.m. Monday. CTA buses will provide shuttle service between Howard and Davis and make stops near each of the affectd stations.
The actual roll-ins will happen Saturday — between 2 and 4 p.m. at Dempster and between 6 and 8 p.m. at Grove.
The city plans to have a live webcam view available of the work on Grove.
The $15 million project to replace the three century-old viaducts is intended to reduce slow zones and improve travel times on the Purple Line.
Dempster Street closed to traffic from Chicago to Sherman Avenues at 7 a.m. today and will remain closed until 5 p.m. Tuesday. Grove Street is partially closed now and will shut completely at 7 p.m. today and remain closed until 7 a.m. Monday.
