north side, running on nearly a straight line and gradient to Fifth Avenue, joining it just west of the school house. (Diagram No. 4.) The lower portion would become the continuation of Forbes Street, and should be raised at Brady Street about 17 feet, or so much that the gradient on Brady Street, up from Forbes Street under the proposed high-level street to Fifth Avenue, will not be over 6 or 7 per cent. A good gradient will still be possible on the approach from Forbes Street to the Twenty-second Street bridge, and the Forbes Street gradient, down from Seneca Street, will be much reduced. These changes will greatly improve the means of access to the Twenty-second Street bridge.
On Forbes Street, just west of Craft Avenue, there is a bad gradient for a main thoroughfare (about 6-1/2 per cent) which is not easy to improve; but the above cross connection at Brady Street will give a through line to the East End via the Forbes Street artery and Fifth Avenue, with a maximum gradient of about 4-1/2 per cent (on the Soho hill).

12. Fifth Avenue - Center Avenue Connection at Soho. -- As a main thoroughfare feeding Minersville and the northern part of the Hill District, either from the South Side via the Twenty-second Street bridge, or from the Point District via Fifth Avenue or Forbes Street, a connection is needed on a reasonable gradient from Fifth Avenue to Center Avenue through the valley south of Soho hill. Such a street (Diagram No. 5) could leave Fifth Avenue at Jumonville Street, start along the location of Wyandotte Street, then curve
