From southeast to northwest, Cleveland is traversed by the winding Cuyahoga river valley, which, while it provides the railroads with an effective entrance to the city, cuts it into two distinct districts as far as vehicular traffic is concerned. To provide crossings over the river and its wide valley, several bridges have been builds, notably the Detroit-superior Bridge near the lakefront and the central viaduct to the south. After 25 years of study on viaduct to connect Lorain avenue on the west of the river with the district to the east, in The Course of which time the project was once abounded after bonds had actually been voted for construction, the citizens of Cleveland are opening, the first week in the November, a $6500000 viaduct 5,865 ft. long, with its eastern terminus at central avenue. Dr. Watson's interest in the project has been continuos since its inception.
