the south abutment of the High Level Bridge and the river pier on the south side, the cast iron arch and road-way are nearly completed, and the second arch will be in progress in the course of a few weeks. From the middle of the first arch, the line curves to a temporary timber viaduct erected along the west side of the intended bridge. The height of this viaduct is one hundred and twenty feet to the level of the rails; it is built upon piles, which are driven between thirty and forty feet into the bed of the river. Its stability was sufficiently tested on Monday, when Captain Leffan (sic), the Government Inspector of Railways, examined it preparatory to the opening. On that day, two powerful engines weighing upwards of seventy tons, traversed it at different degrees of speed for between two and three hours; the weight would be about one ton to a foot, being four or five times greater than the temporary structure will ever be required to bear, and the result was, in the highest degree, satisfactory.
