The last covered wooden bridge over the Weirs Channel. The first had been built in 1804, at the cost of the life of a Captain Stephen Mead of the Weirs, who died from a fall from the bridge durings its construction. The second was built in 1833, when it became neccesary for the Winnipisiogee Steamboat company, owners of the Belknap, the first steamer on Winnipesaukee, to "raise and make such alterations in the Bridge at the Wares, at the outlet of the lake, as will be found Necessciry in order for the safe passage of the Said Boat over the falls at said outlet at all times."
From a stereoview photographed and published by W.L. Wilder, Laconia, N.H, and titled on the reverse side "Outlet of Lake Winnipesaukee". The man in the photograph is reclining on the ground in the area of what is today's Citgo gas station and looking North towards what is now Endicott Rock Park. The "Old Red House" is the house to the left of the covered bridge, on the West side of the Weirs Channel. The name or purpose of the house in the foreground is unknown. The photo was probably taken in the late 1870's, and certainly before 1883, when the bridge was replaced with a steel truss structure.
Regarding the Old Red House, here is an interesting excerpt from Warren Huse's The Weirs, p 26: Torn down in 1902, the house was old long before the Weirs came into prominence as a summer resort in the late 1870's, "when the place was little more than a cow pasture with a plank walk extending a few feet on the side of the lake and known to the traveling public as Weirs Steamboat Landing." The Old Red House was an important trading post. "Over its counter has been sold in years gone by many dollars worth of West India goods, etc., to say nothing of many gallons of old New England rum."
The drawing of the covered bridge, below, is done looking South, in the opposite perspective from the Stereoview, and shows to the left of the bridge, the house with the single chimney that was on the East side of the Weirs channel.
