northern end of the Garden were approved early in the year, 
and the contract for the execution of the work was awarded 
by the Commissioner of Parks to Mr. Frederic Koopman; 
construction was begun in May and has since continued. 
This bridge is now very nearly completed, only some details 
of finish being needed. 
Work on the bridge which is to carry the driveway and 
path-system of the Mosholu Parkway into the Garden over 
the right-of-way of the New York Central and Hudson River 
Railroad Company, at a point opposite the west end of the 
museum building, was commenced in the autumn under a con- 
tract of the Department of Parks, and the construction of the 
abutment on the west side of the railroad is going forward, 
but work has not yet been commenced upon the abutment on 
the Garden side of the railroad. Space in the planted border 
along the railroad for this abutment was made early in the 
fall by moving the trees and shrubs which would come in the 
way of construction operations. Considerable work has also 
been done upon the driveway approaches to this bridge and 
upon their connection with parts of the road-system already 
built. 
Plans for the five-arched rubble stone bridge to carry the 
main driveway across the Bronx River and its valley, at a 
point about 500 feet north of the present ‘‘ Blue Bridge,” 
were approved late in the year; and a contract was awarded 
by the Commissioners of Parks to Mr. F. Leahy for the sum 
of $69,000. The work may be completed in about a year. 
Plans for the bridge to carry the driveway over the valley 
of the two lakes northeast of the museum building have been 
prepared, but an additional appropriation will be necessary 
to carry them into effect. 
The wooden ‘“‘ Blue Bridge” across the river at the nor- 
thern end of the hemlock forest has been keptin repair by the 
Commissioner of Parks.
