The Span Poem by William Calvert

I stand at the center of my span
And watch the river below
It's water's constant moving
Like time it never slows

And as I stand and reflect
Of what lies on either side
On one shore lies what is past
The other what the future hides

If I step back into the past
Could it ever be the same
Can dreams of yesterday
Somehow be maintained

And if I step onto future's shore
Will I be able to find my way
A path unknown to travel
Leading us ever forward into the unseen day

Chained here like a prisoner
Between the two shores I stand
Trapped between past and future
Will I forever stay here on my  span

So now the time has come to leave  
To future's shore I go
Time always moves forward
Like the waters endless flow
But where this path will lead me
One day I'm sure to  know
