Here's a description of the image:

The image is a black and white, inverted photograph of the Charles River Bridge under construction. The image is inverted, meaning the dark areas are light and vice-versa. The bridge is the main focus and stretches across the frame. It consists of several large arches, with scaffolding and construction equipment covering it. There are cranes, ladders, and what appear to be wooden support structures.

Below the bridge, there are horse-drawn carriages and some early automobiles traveling on a road or street. There are also railway tracks running along the road.

The sky is dark, contrasting with the lighter tones of the bridge and the surrounding area. The text at the bottom of the image reads "Charles River Bridge, Progress View" and "Oct. 31. 10". There is also a number "7480".

Overall Impression:

The image is a negative print of a historical photograph, capturing the progress of the construction of the Charles River Bridge. It's a busy scene, with a focus on the bridge and surrounding infrastructure.

Key Elements:

• The Bridge: The bridge is the main focus. It's under construction, and we see the arched spans with the scaffolding and supports. Some parts of the bridge are complete, while others are still in progress.
• Construction Activity: There are numerous workers visible, some on the bridge itself. Scaffolding and construction materials abound, indicating active building work. Cranes are also visible.
• Transportation: Below the bridge, a road with railway lines. Horse-drawn carriages and early automobiles are moving along the road. The presence of the vehicles adds to the historical context.
• Atmosphere: The negative print gives the image a distinct look. The sky is a dark gray, contrasted by the light-colored bridge elements and construction details. This emphasizes the bridge against the dark sky.
• Text and Date: In the bottom left of the image, it is written "Charles River Bridge, Progress View". In the bottom right corner there is a date "Oct. 31.10".

Overall, it's a valuable historical document, showing the construction process and the transportation methods used during that period.
